My Youngest sister has been a member of Weight Watchers (WW) for many years. It has worked well for her, and continues to do so. The WW members have discussion threads where they talk about how to compute Weight Watchers points from food labels. The use of grams and Calories (versus calories) and kilojoules is a perennial topic for discussion. Here is an entry by SCHILA which my sister shared with me concerning an Italian food label:

This causes a face-palm. I realize that it’s not her fault, it’s our lack of the exclusive use of the metric system in the US, and how the incompatible mixture of metric and non-metric units pervades our culture which is to blame. One can immediately see that the Nutritional Information (NI) is actually all metric—in a sense. The Calorie is a pre-SI unit of energy, which was replaced by the Joule in 1948. The Calorie was “metric” 65 years ago.

According to Wikipedia:

Definitions of the calorie fall into two classes:

  • The small calorie or gram calorie (symbol: cal)[2] approximates the energy needed to increase the temperature of 1 gram of water by 1 °C at standard atmospheric pressure (101.325 kPa). This is approximately 4.2 joules.
  • The large calorie, kilogram calorie, dietary calorie, nutritionist’s calorie or food calorie (symbol: Cal)[2] approximates the energy needed to increase the temperature of 1 kilogram of water by 1 °C. This is exactly 1,000 small calories or approximately 4.2 kilojoules.

The difference between a calorie and a Calorie is a factor of 1000 in the US. Why shouldn’t SCHILA be confused. The label has Cal 122 KCAL which is a capitalized Calorie abbreviation, which then tries to make it more understandable by putting it in all caps as KCAL, which of course could be confused for Kilo-Kilo-calories. No wonder the poor woman is on a discussion thread asking for help. The logical solution to me is to be done with calories and Calories (1000 calories or a kilocalorie), switch to SI (official metric) and use kilojoules—like the rest of the world.

Here is a package of licorice from Australia (courtesy of Mike Joy). It is advertised as one meter long. The front of the package has only one mass (weight) given: 120 grams. That’s it!  You don’t need any other information.

On the back the nutritional information is:

Nutrional Label for Australian Licorice

We see that the Australian food vendors also use untidy numbers like 4.8 servings in a package. The serving size is 25 grams which is 353 kilojoules, that’s it! Every other description: protein, sugar, sodium and so on are broken out in grams or milligrams.

Ok, how many kJ’s do you get a day? Well in the US I generally see 2000 Calories on food labels as the recommended daily intake. This works out to about 8375 kilojoules. Look how many kJ’s you get! Doesn’t that sound better than 2000 Calories? Here is a short table to give you an idea of the range of kJ’s and the old way:

5000 kilojoules is 1194 Calories (1200)
5500 kilojoules is 1313 Calories (1300)
6000 kilojoules is 1433 Calories (1400)
6500 kilojoules is 1552 Calories (1500)
7000 kilojoules is 1671 Calories (1600)
8000 kilojoules is 1910 Calories (1900)
8500 kilojoules is 2030 Calories (2000)

So for many WW members somewhere between 5000 and 8500 kJ’s is the range for you to think about. The Australian Government has recently sponsored a push to get Australians to eat around 8700 kilojoules per day. Here is a page from their website:

So what does the back of a licorice label in the US look like? This is from Twizzler’s web page:

Not all that that different, other than the use of Calories (i.e. kilocalories). So what’s the big deal? Well, the big deal is that because the US is not exclusively metric like Australia, very few Americans have any idea what a gram is. (It is about the weight of a plain chocolate m&m). This lack of exclusive metric adoption in the US obscures dietary data that is readily available. Any confusion will cause many people to just not bother with the nutritional information.

Should we go back to Ye Olde English units on food packaging?—well they’re actually Olde English sizes used prior to the English reforming their units in 19th Century, but we’ll let that pass for now. Some people who believe claim they are trying to help the public say yes. These people are from the anti-metric Wall Street Journal, and like James Taranto are there to yelp—I mean “help.” Their anti-metric “Numbers Guy” seems to be more interested in running a numbers racket than actually enlightening people about numbers.

When the Wall Street Journal is on the side of the Center for Science in the Public Interest–watch out–what they have in mind is not in the public interest. They want teaspoons and tablespoons back! I’ve already written about how confusion between the two, and the lack of metric in the US kills about 98,000 persons in the US each year. It would also make our nutritional labeling completely incompatible with the rest of the world—which all use metric. They want to swap mass (grams) for volume (Tsp, Tbl)? Isn’t it bad enough we use ounces interchangeably for weight and volume already?  Do you think 8 (by weight) ounces of cheese doodles is a cup (8 oz by volume) of them? The Wall Street Journal has never found a bad Weights and Measures idea they didn’t like.

The frustration the rest of the world has with us is completely understandable and surfaces on the WW discussion thread:

All I can say is You Go Girl!

What started this WW discussion thread was a question about the nutrition label on the back of an Italian food product. If all our US packaging was in teaspoons and tablespoons, and grams became even more unfamiliar, this would further alienate us from 95% of the worlds population and their products. I guess the Wall Street Journal just can’t help themselves—they like trade barriers. Once again the inability of our legislators to pass mandatory metric only legislation for the US, with a plan, and funding, and so on, hurts the nations physical and economic health. Congress has been goofing around since 1866 thinking about metric, isn’t it time they finally got to work and dealt with the metrication issue?

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.


The third book is not of direct importance to metric education. It is called Death By A Thousand Cuts, A Secret History of the Metric System in The United States. 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.

Orwell and The Metric System

George Orwell (1903-1950)

By The Metric Maven

Bulldog Edition

As I wandered the halls of my Junior High as a boy, I saw two books over and over. One was George Orwell’s 1984 and the other was his book Animal Farm. They were required reading for an English class. One I was never in.  I did not read either book until a few years back when I read 1984. When I did, I was surprised at the anti-metric viewpoint Orwell articulated. Christopher Hitchens in his book Why Orwell Matters states on page 128:

“And he had a strong conviction that the metric system — which was to become such a toxic issue in England in the early years of this millennium — was somehow ill-suited to humans, let alone Englishmen.”

He conceded that for industrial and scientific purposes the metric scheme was necessary. However:

“The metric system does not possess, or had not succeeded in establishing, a large number of units that can be visualized. There is, for instance, effectively no unit between the metre, which is more than a yard, and the centimeter, which is less than half an inch. In English your can describe someone as being five feet three inches high….but I have never heard a Frenchman say, ‘He is a hundred and forty-two centimeters high’; it would not convey any visual image.” (page 128-129)

Hitchens discusses Orwell’s literary objections that consist of the the fact that measurements such as the pint, quart, foot and so on are much shorter to pronounce than liter, meter and such. It is the same complains I heard when reading objections offered in the 19th century by “defenders of Anglo-Saxon measures.” Hitchens then states:

“…he [Orwell] was protesting to his agent that the American publishers of Nineteen Eighty-Four had, at the proof stage, rendered all his metric measurements into the old form: ‘The use of the metric system was part of the buildup and I don’t want it changed if avoidable.” It’s easy to see why. When Winston Smith goes slumming with the proles in Chapter Eight, he gets into a futile conversation with an addled old man whose memory — so crucial to Winston — is a wreck except for unimportant details:

“I arst you civil enough, didn’t I?’ said the old man, straightening his shoulders pugnaciously. ‘You telling me you ain’t got a pint mug in the ‘ole bleeding boozer?’

‘And waht in hell’s name is a pint?’ said the barman, leaning forward with the tips of his fingers on the container.

‘ ‘Ark at ‘im. Call ‘isself a barman and don’t know what a pint is! Why, a pint’s the ‘alf of a quart and there’s four quarts to the gallon. “Ave to tach you the A, B, C, next.”

‘Never ‘eard of ’em,’ the barman said shortly. “Litre and half litre — that’s all we serve.’

Hitchens states: “..Orwell succeeds in depicting a sodden deracinated people who have been forcibly alienated from the familiar things that were near and dear to them.”

I have heard Hitchens relate that he was puzzled by Orwell’s skepticism toward the metric system. That in turn, surprised me. When I first ran across Orwell’s anti-metric position, It struck me as a common problem that many scholars encounter, and to which they are blind. This is the problem where their thesis for a particular circumstance is applied outside of the environment in which it makes sense. James Frazer, author of the Golden Bough, saw magic everywhere, and could not help but stretch the bounds of his thesis to the point where one might see the whole of humanity acting in response to magical impulses. Richard Dawkins and his idea of Selfish Genes controlling humanity is another. Or Population Geneticist George Price, who became consumed by the idea that we are all evolutionary automatons.

What was the thesis of Orwells’ that acted like a literary version of The Blob, and finally oozed over the metric system?  It is the idea that the control of language was the weapon used by Big Brother to enslave the population. Big Brother was slowly eliminating words that could express complicated human emotions and societal ideas. Big Brother was distilling the dictionary down from a massive tome, to a pamphlet. The purpose of this was to make the public less and less articulate, and unable to express themselves. This was the means by which he would reduce humanity to a useful primate, somewhere just above a chimpanzee using sign language, but much more pliable for enslavement. Orwell seems to simply apply  his thesis to measurement units. If a group is trying to eliminate numerous measurement units, then it’s the same activity, with the same sinister purpose as was done with literature. He equates literature with scientific measurement. Now that’s serious pigfish.  More measurement units good, less measurement units bad. Orwell’s thinking–flawed.

In my view, Orwell is also a good example of what C.P. Snow famously called “The Two Cultures.” Snow saw two groups, which can be broadly called literary intellectuals and scientific intellectuals, existing with a deep intellectual chasm between them. Orwell is clearly in the literary camp, and appears to be almost scientifically illiterate. Whereas society may have a fractal nature, the mass of a ball bearing does not; it has one value. The idea that assigning a multitude of unequal units to describe a ball bearing’s mass, will in turn, increase one’s understanding of the value of its mass, is anathema to a common understanding of the quantity. Engineering and Science rely on consistent and universal measurement to function. Without measurement consensus, scientific endeavors would grind to a halt as no one could repeat experiments.

If I had the opportunity, I would have given Mr. Orwell a bit of homework that just might have changed his view about metric. I would have had him read John Quincy Adams Report on Measures. It is clear to anyone reading it (except for its author, which is very odd) that the almost uncountable number of units he quotes produce nothing but confusion, and do not lead to clarity. Here is part of ONE page from the voluminous report:

Earlier John Quincy Adams relates how the French attempted to retain measurement names even as they had simplified the quantities by using grams.

I have used grams in my cooking for about two years now, and I can tell you, grams mean something to me, other quantities are just opaque obfuscation. Orwell’s unfamiliarity with Engineering and Science, and his strange belief that there should be one simple, logical and intuitive measurement system for Engineers and Scientists and a complete non-intuitive free-for-all of units and sizes for the “common person” seems contrary to his stated interests. The one place where reality intrudes and shows no quarter is in measurement. If you cannot be certain how much of a commodity you are purchasing, then you may end up starving. Deliberate confusions of measurement quantities, and unit proliferation, are perhaps the oldest methods employed to cheat one’s fellow person. So would you like to purchase to gold by the pound and sell it by the pound at the same price, when in one case it’s Troy and the other it’s Avoirdupois? Given the choice between this option and in both cases measuring the mass in grams which would you choose?

Mr Orwell did not do humanity a favor by embracing, manifesting and promoting his idea of “Englishness” through measurement confusion. He has hurt Britain, and his influence on thinking in the US has certainly made matters worse. Even worse, he has created an “intellectual refuge for scoundrels,” mantled within anti-authoritarian literature. James Joyce is respected as a literary beacon, but I suspect he would write useless books on plumbing. Orwell may have exceptional and important observations about human society, but is obviously feckless when it comes to understanding quantitative measurement.

Believe me, Big Brother would have loved the imperial system, and those struggling against him would have spoken in soft whispers about metric measurements. The only words that would have been added to Big Brothers dictionary would have been perches, pottles, casks, firkins, and hogsheads ad nausium. Big Brother will determine the dimensions of the world, and with a proliferation of units, change it at will. But Orwell leaves us with a very slight puzzle about his view of the metric system, In his essay England Your England, he also said this:

One has only to look at their methods of town planning and water supply, their obstinate clinging to everything that is out of date and a nuisance, a spelling system that defies analysis, and a system of weights and measures that is intelligible only to  the compilers of arithmetic books, to see how little they care about mere efficiency.

In the context of this essay, which appears to have been written as a semi-patriotic paean of praise for England as the Nazis rained bombs upon his nation, I think he might be using this statement to tap into some type of “English Pride,” in the same manner that I hear some ignorant Americans gleefully express the belief that our Olde English Measurements are what make us “unique” and “exceptional.” I’m not certain if Orwell’s statement on weights and measures is a condemnation, or a dog-whistle statement to the British, which is meant to endear them to themselves. Either way, George Orwell did not understand that a measurement system is not the same as a vocabulary. A vocabulary maps words with the infinite variety of human emotions and metaphor. A measurement system maps numbers to a single reality in nature. The reduction of vocabulary reduces the ability of a population to express itself socially. The proliferation of measurement units decreases the ability of a population to describe the physical world in a coherent manner. The metric system was created in response to exactly this problem. The physical world is not the same as the emotional world. Mr Orwell dealt with the latter, but clearly had little understanding of the former, or he would have embraced the metric system.
