# Bonfire of The Vanity Units

By The Metric Maven

Bulldog Edition

John Bemelmans Marciano gave a lecture on CSPAN’s BOOK TV (2014-08-12) to promote his book Whatever Happened To The Metric System?, which neither answers the proposed question, nor discusses the metric system itself. In his lecture, Marciano makes straw-man statements like:

The reason  that the metric system was needed in the first place was that decimals aren’t such a great way to divide things. Have you ever tried dividing a pizza into ten slices or five slices it’s not very easy. It’s really easy in four, six, eight, if you have a Sicilian pie you might do it in twelve or sixteen. … the only thing that ten is good for is counting on your fingers. ….they’re excellent for tallying, when you have to have a running tally of something, but they’re just not good for fractions.

Anyone who casually is acquainted with arithmetic will see that decimals are one of the most useful creations of mathematics. They are straightforward in magnitude, whereas fractions are an incomplete thought. The only way to further simplify numerical expression is with measures that can eliminate decimal points in everyday life. The metric system does this with grams, milliliters, and millimeters. The use of integer values in place of fractions is an upgrade from an abacus to a modern computer.  Marciano seems to have done little research on the metric system, or is willfully ignorant.

Marciano continues with both a revisionist and radically incomplete history of the metric system.  “So whereas decimals were supposed to make math and currency and everything available to everybody, it actually just made it available only to people who were really truly well educated.” Marciano appears to be implying that decimals were created and adopted so the power elite can rule over the innumerate populace. They are so complicated of a concept that only those who are highly educated can comprehend them? How on Earth does anyone use decimal currency? For Marciano, metric is not a commie plot, but a capitalist plot?  Decimals are apparently an antidemocratic force in our society?

He goes on to argue that the return of kings to Europe was very sad for John Quincy Adams “who had about the biggest crush on the metric system of anyone.” That statement is amazingly off the mark, perhaps by a few Gigameters? You are invited to read my essay about John Quincy Adams, and you will find that JQA had nothing remotely like a “crush” on the metric system, which is well documented in his own words. John Quincy Adams was the John Bemelmans Marciano of the 19th Century. Marciano clearly did not spend any time reading John Quincy Adams’ Report on Weights and Measures, or he would have known this. But this does not stop Maricano from interpreting it: “He [JQA] actually wrote, while he was Secretary of State, the greatest work ever written about measurement, and he talked about all the great things about the metric system….” JBM’s assertions are clearly at odds with JQA’s Report.

Marciano protests too much when, after he was asked by an audience member if he is anti-metric, he states:  “I am pro-metric, but I am also pro-customary measures. … I think we should keep it all.”

I see this statement as completely disingenuous. I’ve read Marciano’s book and his online editorials, listened to his NPR interview and this BookTV presentation. Marciano’s pro-metric assertion is doublespeak. Keep it all? Is Marciano for everyone choosing an old measure and using it if they want?

Marciano then states, to prove his pro-metric bone fides, that he thinks liquid measures should be metric. Marciano then reaches down and produces a bottle and states:

One fascinating thing of measurement is the growler. The growler started up… the growler is actually an old system of measure that was revived .. I think they were Wyoming brewers who..who restarted it. A growler is half a gallon .. its filled with four pints .. what I think the growler speaks to is that the craft brewing movement came out of the U.S. and it’s… I think the reason that the pint gets to be used is …it seems like this more honest system of measurement. Ben and Jerry’s when they wanted to have sort of a more .. homespun they revived the idea of using a pint for ice cream .. a pint really sounds like ..it comes right off of the farm. …almost all of our dairy is still in — solely in customary measures.  ..when you realize it’s still ingrained in people’s minds is when you actually buy in a whole unit. You’re not just buying 14 ounces of something you’re buying a pint of it, a quart of it, you’re buying a half-gallon of it. If it’s just something like 14 ounces or you know point four six milliliters we just pay no attention to it.

Well, Marciano stops there when talking about liquid measures. I don’t see any argument using actual numbers with the metric system, or where he thinks one should use metric units for liquid measures. (Perhaps he could mention mis-dosages?) He does not follow through with his assertion that he is pro-metric for liquid measures. Marciano instead explains why people in the U.S.  just love the current mess. Marciano’s final statement  about 0.46 milliliters could be taken as hyperbole for how clueless people are about measures, or worst of all, it could be he is numerically clueless that 0.46 mL is 460 microliters, a value that would probably not be found on a store shelf.

What caught my attention more than all of the muddled assertions, was the notion of a growler. When I first heard Marciano discuss this unit, I figured it was just one more of the thousands and thousands of confusing pre-metric units that have existed in history. I have a number of engineering references for measurement units, and none of them mention a growler. I looked on Wikipedia, no entry for a measurement unit called a growler exists, but there is an entry under “beer bottle” with a reference to 64 ounce or 32 ounce growlers. The 32 ounce is sometimes called a howler for half-growler. This smells like marketing, and not measurement. The growler is almost certainly a made-up vanity unit for the microbrewing industry, which does not see the irony in using a metric prefix for self-identification and then marketing in Ye Olde English.

The growler is just a vanity unit, made up for marketing purposes. It appeals to novelty/pseudo-nostalgia and has no standing for measurement. It’s no different than using coffee speak to order  a tall cafee au lait dry single skinny. A growler is simply a hipster vanity unit.

There is a long worn pre-metric unit for one-half gallon. It is the pottle, and it is also equal to 32 gills to make the quantity plain for my U.S. readers who we can assume understand English measures and not metric. As Marciano is for all of them, perhaps we should include all gills:

This reference from 1850 helps us to understand this new and important faux unit—the growler—even if there is no entry for it. One notes that U.S. measure is Great Britain’s old measure. Because when it comes to measurement, Marciano is for all of them, we should include all known growler quantities. Assuming a 32 gill growler:

• British Growler = 4545 mL
• Irish Growler = 3263 mL
• Scottish Growler = 3389 mL
• U.S. Growler =  3785 mL

So the growler varies from 3.26 liters to 4.55 liters. Yes, clearly the old measures are, as Marciano asserts, much more honest. Perhaps we should create a unit called the Enron?

I’m very surprised that an expert on measures like Marciano missed pointing this out to his audience, especially when following up on his assertion that he saw the metric system as a better idea for liquid measures. Why the imaginary growler? Perhaps pottle doesn’t have the marketing appeal of a growler and sounds too much like what one does after drinking said imaginary unit. Marciano likes to use Tom Wolfe as an A-list metric opponent, but Marciano, despite his protestations, seems to relish representing contemporary Bonfire of the Vanity Units.

# The New Traditionalists

By The Metric Maven

Bulldog Edition

One of the great legacies of Pat Naughtin, in  my opinion, is his willingness to examine traditional usage of the metric system, and suggest improvements. Before I encountered his writings and lectures, I had been inculcated with the idea that when one crosses a prefix boundary, there should be an abrupt transition to the next prefix. If my last data point was 900 meters, and the next data point is 1200 meters, then one should write down 1.2 km instead of 1200 meters. I believed that this rule had been carefully considered by academics at my university, who were much wiser than myself.  Their other admonition, no concatenated prefixes, no micromicro or kilomega, made good sense and so I thoughtlessly swallowed their prescribed use of the metric system whole. Over the next couple of decades of my career, this metric dogma had become fixed. Because I mostly used inches, pounds and such at my place of employment, metric was just an internal abstract concern. My theoretical work was computed in pidgin metric, but the final number would be expressed in Ye Olde English representation. Pat Naughtin encouraged me to question my basic assumptions about metric usage. My consulting work gave me the opportunity to embrace metric exclusively. I was then able to try out Naughtin’s suggestions and develop my own thoughts. It was liberating.

From the beginning of my blog, I have made a considerable number of metric proposals. Some are ideas that would require government coordination to achieve, others could be adopted by individuals. Here is a list:

Some of these suggestions were met with minor brouhaha’s. Often BIPM documentation was cited, chapter and verse, and displeasure expressed. I continue to use these, and seldom do readers make much of a fuss these days. These have become so comfortable, they’re invisible to me.  So it came as a bit of a surprise when I read this from a metric advocate[1]:

“Don’t use centimeters!” “Use only the millimeter!” go the cries from would-be metric purists over which scale of reference to use in a particular measurement situation. Add to these screeds those who would adhere to “units” that find their definitions in metric terms such as “the” Angstrom and “the” micron, and one has a customary system within the SI. This is not the plan envisioned by the architects of the international measurement system. SI units were meant to thrive on newfound logic, not newfound tradition.

The word purist is defined by the Merriam Webster Dictionary as:

a person who has very strong ideas about what is correct or acceptable and who usually opposes changes to traditional methods and practices

This definition applies to someone who opposes change. Eleven examples of suggested change are summarized in the bullet points above. I’m clearly on the side of change. One of the proposals is to eliminate the use of centi. In my view, to argue for the use of centimeters, in the light of the millimeters proven usefulness, is to be a slavish follower of tradition.  A person advocating nothing but the status quo is a purist, but a better term might be New Traditionalist. The archives of the association this New Traditionalist represents, document the anti-utility of centimeters. This hard earned realization has apparently been sacrificed on an altar of tradition and amnesia. The centimeter is back.  Strangely, New Traditionalists do not call for the use of earlier traditional metric quantities, such as the myriameter (10 000 meters), or the double deciliter, demi-deciliter, double centiliter, double gram, demi dekagram, double dekagram, demi hectogram, and so on. A myriameter is based on ten, just like the centimeter, why don’t we need a myriameter?

At least he agrees with me that the angstrom and micron should be banished—I think. The prose is rather opaque. I guess he is saying that people like myself are trying to create a replacement tradition without any rational basis behind it? I have explained my reasons for the proposed changes in considerable detail. I’ve provided links in the bullet points above to blogs that explain my rationals.

Only a New Traditionalist, would defend a “…plan envisioned by the architects of the international measurement system” that includes the use of tonne with SI. First, tonne is easily confused with the Ye Olde English ton (long or short) because it is a homophone (i.e both ton and tonne have the same pronunciation). Second, the use of a metric prefix with tonne, is obfuscating. For example, the use of Kilotonnes undermines numerical comprehension. When one encounters 39.37  Kilotonnes, and then wants to actually use this value in a metric computation, it must be first be recognized that a tonne is a Megagram. Then we apply the Kilo prefix to obtain KiloMegagram. This violates the BIPM commandment “thou shalt not concatenate prefixes,” but is accepted for use with SI? This is the plan envisioned by the architects of SI?—based on logic?

The simplicity of the metric system is buried when one has to decode an “accepted” metric expression. For example, the number of grams in 4.7 Gigagrams is straightforward, it is 4.7 x 109 grams, the number of grams in 4.7 Kilotonnes is not. New Traditionalists apparently are fine with the idea that the tonne is not part of SI, but is accepted for use with SI. It is ignored that when tonne is used with metric prefixes, it automatically violates the rule against concatenating prefixes. This is a practice the New Traditionalists apparently embrace with exaltation as part of “..the plan envisioned by the architects of of the international measurement system.” The lack of rational usage one finds with the implementation of the tonne in SI is epic. The dead weight of tradition is obvious when the tonne is logically examined. It appears New Traditionalists want to save SI from improvement and clarity. Tonne is clearly “a customary system within the SI”, but there is no objection from the New Traditionalists.

It is further stated:

However, there is a certain amount of facility that one, both as a user of decimal arithmetic and also eventually as an SI citizen, develops in placing the decimal point.

The fraction or multiple of the base unit should be selected by the eye and the mind, and not by heraldic prescription.

I guess the first statement is simply a claim that it is easier to use decimals when one uses decimals? If one doesn’t need to use decimals at all, isn’t that easier?—and in the case of millimeters for everyday work—empirically demonstrated to decrease errors?  This does not seem apparent to New Traditionalists. I find this blind spot as baffling as those who don’t see how much easier decimals are to use than fractions. Everyday people have the choice of using the side of a ruler with decimals, or a side with fractions. People in the U.S. continue to use the ruler side with fractions instead of the side with decimals.  I’m sure New Traditionalists find the fact that people don’t seem to see this obvious decimal simplicity, and use the decimal/centimeter side of a US ruler, as confounding as I find the New Traditionalists not realizing that integers are simpler than decimals, and therefore millimeters are the obvious choice.

Centimeters seem to have become a kind of fetish for The New Traditionalists. Curiously, there seems to be no fetish for centigrams dekagrams or centiliters. No chemist, or average person argues that we need to use centiliters with decimals instead of milliliters alone for volume, or centigrams dekagrams with decimals in place of grams. Why would we complicate metric length by using centimeters with decimals, when millimeters perform the same simplifying function as milliliters and grams? The choice of milliliters allows for the use of whole numbers when dealing with volume, as does the use of grams for mass. Millimeters should be an obvious choice, but for New Traditionalists, they seem to be as un-obvious as decimals are for the users of Ye Olde English fractions.

Decimal representation is absolutely essential to my engineering work, and when needed, nothing better exists. But for everyday use, it should be clear to any average person that using whole numbers on a millimeter scale is much easier than using whole numbers combined with a fraction involving 1/2, 1/4, 1/8 or 1/16. A millimeter ruler automatically has a precision of 1/25th of an inch!—and it’s much simpler to use! I don’t see how any of my metric usage suggestions are a form of medieval “heraldic prescription,” that might have been produced at an SCA meeting. As longtime readers know, I’m very much against Ye Olde English.

The New Traditionalist further states:

It is not expected that humankind will memorize the entire list [of prefixes] and be prepared to refer to it mentally when challenged to select a frame of reference.

Humankind faces a considerable number of challenges that require as much numeracy as possible—if we are to confront them rationally. Global Warming is an existential threat. The late Pat Naughtin demonstrated that with well selected metric prefixes, quantities relevant to understanding global warming, can be readily understood in relation to one another and evaluated by anyone.

Currently sea level is rising about 3-4 millimeters per year. Since 1880, tide gauge records show there has been a 200 millimeter cumulative increase in sea level. The total amount of water in the Earth’s ocean is about 1386 Exaliters. The area of the Earth’s ocean is about 335 square Megameters. With these values, we can compute an average ocean depth of about 4.14 Km. The 335 Mm2 area of the global ocean has increased its depth by 200 mm. If we multiply the total area of the ocean by the increased depth due to global warming, we arrive at the total increase in the ocean’s volume. This works out to an additional volume of about 67 Petaliters over the last century. The total amount of fresh water on Earth is about 109 Petaliters. The majority of the water entering the oceans is from melted ice. This water is drinkable; but when it is mixed with the ocean it becomes unfit for human consumption. There is not enough fresh water to dilute the ocean enough to make it drinkable. I made this point in my essay To Infinity….and Beyond. The additional amount of fresh water lost to our salt water ocean each year is about 670 Teraliters. This is drinkable water lost to humanity because of global warming. The amount of drinkable water on Earth is already critical. A minute amount of this increase in sea level is from the warming of the oceans, but with these values, and metric numeracy, one can readily estimate important quantities. The loss of naturally stored drinkable water each year is clearly an important quantity.

In this country, we readily make up songs to recall the names of all the 50 states. It would seem to me that developing a song, and teaching all 16 metric prefixes, from grade school through high school, is not asking much. Each prefix could have the size of an object in the song for reference. In my view this would be a much more worthwhile exercise than using a song to learn the names of the first 44 Presidents of the U.S. We can all recite our abc’s, and their are only 26 of them. Sixteen metric prefixes should not be a problem. I cannot see why New Traditionalists would excuse our populace from naming and committing to memory, all the metric prefixes, and understand their relationships. The issues we face as humans are more and more intertwined with science and engineering. The more directly a populace can understand quantities involving peak oil and energy or water resources and global warming, the better chance we have of making informed decisions. Rather than passively deferring these decisions to others, who may have conflicts of interest, people need to be informed. Promoting an ignorance of large metric prefixes, is truly the purview of New Traditionalists. Exclusively using only the prefixes that existed before the microscope and telescope were invented, only preserves the limited intellectual scope found within the mind of the 17th century, when we are confronted with 21st century problems.

When I look at the metric system, I see possibilities for improvement and streamlining. I argue for my position as rationally as possible. New Traditionalists embrace stasis and the apotheosis of current BIPM rulings. When people in the U.S. started using the capital letter L for liter when writing milliliters (mL), I’m sure there were New Traditionalists who were against this altered usage worldwide. Eventually the improved clarity of the new symbolism was realized and accepted. Reflexively defending the status quo, when better options have been proposed, is defending tradition and thoughtless obedience. It is the opposite of scientific discourse, it is theological discourse.
