Metric Day Edition

I’ve had a difficult time coming up with a subject for this year’s Metric Day essay, so here are my random observations since the last Metric Day.

The two metric stories which dominated what little publicity metric received over the last year were 1) Lincoln Chafee mentioning that he thought the U.S. should become metric and 2) The possible replacement of the only metric road signs in the U.S. with non-metric versions.

Lincoln Chafee tossed out the idea of converting to the metric system as a bit of a throw-away line, but the metriphobic press reacted like a duck on a June bug. Anti-metric poster-child John Bemelmans Marciano penned No, America shouldn’t go metric with all the Pavlovian fervor he could muster. CNN was only too willing to publish Marciano’s reactionary polemic. John Stewart of The Daily Show, who, like any comedian, goes for laughs first, and thoughtfulness—whenever it works out, said this to his two million viewers:

Jon Stewart: Alright Chafs, hit us with your Hillary crushing vision for America.

Video of Chafee: Here’s a bold embrace of internationalism. Let’s join the rest of the world and go metric.

[Audience Laughter] Stewart blankly stares at the camera.

Jon Stewart: The time has come America, to switch to centimeters. [Audience Laughter] And why use cars when we can relax and exercise by traveling only by recumbent bicycle. Wait where’s everybody going I haven’t passed around my homemade .. blondies yet. Why would you launch your campaign by evoking one of Jimmy Carter’s most notable non-hostage related failures?!

Video of Chafee: Only Myanmar, Liberia and The United States aren’t metric…

Jon Stewart: You want to be our president and yet you don’t know we don’t give two shits about other countries? Or…or if I may, to put that in metric terms, point oh two millifeces.

Which I’m sure Mr. Stewart knows is actually 20 microfeces. Of course Stewart would use centimeters, without any irony, and assert that President Carter was actively for the metric system (he wasn’t, he’s a Metric Philosopher).  Beating up on the metric system is fun!

Stewart has also gone after metric ignorance at times, such as when he lampooned Rick Sanchez for asking how high nine meters is in English, but this segment only pointed out that England actually uses metric.

Not all the coverage was uniformly negative. NBC News on their website had the headline: A Case for Liter-Ship: Advocates Cheer Lincoln Chafee’s Metric Proposal. CNN had Lincoln Chafee: Go bold, go metric.

The changing of metric signs on I-19 provided an opportunity for CNN to publish the lack of the metric system in the U.S. as “A Great American Story” entitled Refusing to Give an Inch — Why America is Anti-Metric. This vapid and vacuous article did not educate or inform, it merely parroted the conventional mythological narrative, and provided yet another soap box for John Bemelmans Marciano to release incoherent and content free criticism. The I-19 road signs are being changed because they don’t meet new reflectivity requirements. It is interesting there is total silence about the cost of changing the signs because of their reflectivity, but if they were Ye Olde English, and they were to be changed to metric, then metric signs would be “too expensive.” As I said previously, if all the road signs in Arizona need to be replaced, then why not with metric? If not now–then when? Clearly the road sign arguments over cost are just a regressive political position dressed up as “fiscal responsibility.”

I saw a reminder this year that basic roadway measurements are important. In Westwood Massachusetts a bridge which is 3200 mm in height above the roadway (10′ 6″ for those who need two units to describe a distance) often tears the tops off of trucks. This happens often enough that the police have set up a camera to record the intersection and document the truck shredding. Over the years, about one truck per month is decapitated by the bridge. Some truck drivers believe they are going to make it without consulting any arithmetic and discover the hard way that Seeing Is Not Measurement. While implementing metric cannot help truck drivers who estimate distances without numbers, it can make it simpler for those who do.

My attention this metric day is drawn away from the two flash-in-the-pan mainstream metric stories, and to personal everyday hidden stories of metric in the U.S. My friend Lapin has attempted to persuade the principals in his small engineering company to go metric. Lapin pointed out how much easier millimeters are to use, but the metric system was yet again dismissed, and inches remain the default. One person there indicated that the best place for a millimeter only tape measure was inside of a hydraulic press, so that it could be as completely destroyed as possible. Engineers I know who work in Aerospace have long ago given up any thought of a metric switch-over. These stories clearly tell me that without government intervention, a U.S. metric changeover will not take place in the next 1000 years. The workings of our Frozen Republic are so slow, that it will probably take 1000 years before congress even returns to the issue. The 2013 We The People Petition was summarily dismissed with a missive from the former Director of NIST, that was pure anti-metric Edward Bernays. There appears to be no hope in the U.S. for a metric change-over.

Is there any other possibility? I can think of only one, and, although it’s almost certain not to happen, it probably has a higher probability than the U.S. government affecting change. It is that the rest of the world finally tires of our pig-headedness and directly punishes the U.S. economically for its continued non-use of the metric system. I could still see this failing, as what little manufacturing is left in the U.S. would probably just design one product for the U.S. market and another for any other place in the world they sell goods. Cost is never as important as maintaining the Ye Olde English “Heritage.” Americans are also notorious for resisting any “outside ideas” unless they can quietly co-opt them. After World War II the U.S. created the interstate highway system after experiencing the German Autobahn. There has been very little exposure to efficient use of the metric system in the U.S. and so people either react in a positive way or viscerally in a negative way depending on what their model of truthiness tells them.

There is little to celebrate on this Metric Day other than the simplicity and elegance of a system that is as unknown in the U.S. as fortune cookies are in China.

The first book is titled: Our Crumbling Invisible Infrastructure. It is a succinct set of essays  that explain why the absence of the metric system in the US is detrimental to our personal heath and our economy. These essays are separately available for free on my website,  but the book has them all in one place in print. The book may be purchased from Amazon here.


The second book is titled The Dimensions of the Cosmos. It takes the metric prefixes from yotta to Yocto and uses each metric prefix to describe a metric world. The book has a considerable number of color images to compliment the prose. It has been receiving good reviews. I think would be a great reference for US science teachers. It has a considerable number of scientific factoids and anecdotes that I believe would be of considerable educational use. It is available from Amazon here.

This monograph explains how we have been unable to legally deal with weights and measures in the United States from George Washington, to our current day. This book is also available on Amazon here.

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.
