My Measurements Can Beat Up Your Measurment System

By The Metric Maven

Bulldog Edition

One day while discussing architecture and engineering with Sven, the subject gravitated to Gustave Eiffel (1832-1923), and his iconic tower in Paris. Sven pointed out that The Eiffel Tower is generally called by that name here in the US, but elsewhere was originally known as the 300 Meter Tower. I had no idea. The tower itself was so reviled by the art establishment of the time in Paris that they created “The Committee of Three Hundred,” which symbolically had one member for each meter of the egregious tower’s height. Like any good committee they created a petition which asserted (Wikipedia):

“We, writers, painters, sculptors, architects and passionate devotees of the hitherto untouched beauty of Paris, protest with all our strength, with all our indignation in the name of slighted French taste, against the erection…of this useless and monstrous Eiffel Tower … To bring our arguments home, imagine for a moment a giddy, ridiculous tower dominating Paris like a gigantic black smokestack, crushing under its barbaric bulk Notre Dame, the Tour Saint-Jacques, the Louvre, the Dome of les Invalides, the Arc de Triomphe, all of our humiliated monuments will disappear in this ghastly dream. And for twenty years…we shall see stretching like a blot of ink the hateful shadow of the hateful column of bolted sheet metal”

One had no trouble detecting their displeasure at this creation. It is strangely ironic that the tower had not yet been constructed, and so the artists were all judging from drawings. Eiffel responded by comparing his work with that of the Egyptian pyramids. There was more irony to be found with other people who did more than compare their ideas to the pyramid, but asserted it was the basis for a sacred measure. Charles Piazzi Smyth (1819-1900) was not one to settle for mere similarity. He traveled to Egypt and took measurements of the pyramid, from which he derived the pyramid inch. The pyramid also allowed for the derivation of the pyramid pint and a pyramid temperature scale. The pyramid inch was in C.P. Smyth’s view handed down to us by God himself. The introduction of the metric system in to Britain would therefore be unthinkable. C.P. Smyth continued his anti-metric activities throughout much of his life. He was also one of the Vice Presidents of the International Institute for Preserving and Perfecting Anglo-Saxon Weights and Measures.

The President of this organization was American engineer Charles Latimer (1827-1888). He also had a problem with Gustave Eiffel, and did not like one of his creations: The Statue of Liberty. In a bimonthly publication called the International Standard  they state: “There is only one thing we do not like about the statue: We prefer a statue of liberty measured in good earth-commensurable Anglo-Saxon inches, not in French millimeters, the result of caprice…” This statement was quoted in part five of the newspaper series Everyday Guide to the Metric System published in the late 1970s.

Eiffel’s works were criticized using the metric system in France (The Committee of Three Hundred) and in the US because they were built with the metric system. The more things change the more they remain the same. The World Trade Center twin towers were described by Norman Mailer as two fangs rising up into the New York skyline. They did not fit, he argued, within the wondrous architecture and beautiful skyline which surrounded them. They were a blight on Manhattan. Building One had an antenna which protruded 526 meters from the ground, and building two was 415 meters in height. Very long fangs indeed. The criticisms of the past were long forgotten following September 11, 2001 when they were both destroyed by terrorists.

The discussion of a replacement for the World Trade Center buildings has been politically heated, and took considerable time to begin. The replacement is called One World Trade Center and is scheduled to open in 2014. I was chagrined when I found out its architectural height is 1776 feet. It was like the Eiffel Tower (excuse me the 300 meter tower) and The Statue of Liberty all over again. Measurement units tied to cultural identity, which enforce cultural intransigence concerning the metric system. Denver cannot help being The Mile High City (it was originally the Queen City), nor Colorado being The Kilometer High State, but we could have chosen a different architectural manner to express our “Americaness” other than something as anachronistic as a height in feet, tied to a year associated with the birth of the US. We had a choice, and once again we chose to memorialize the past with anachronistic measure. Will we ever again choose the future?

Whatever Happened To the Metric System?

Guest Book Review By Sven

Is the metrication of a nation a technical exercise, or a social problem? Of course it is both, but in practice, one or the other view predominates. This should be recognized as framing all underlying debate. The classic example of a nation that came late to metric, but approached the transition as a technical hiccup, is now among the most successfully metricated: Australia. The nation that briefly flirted with metrication at about the same time, the 1970s, but dropped it on the dubious grounds that it would have required too much penicillin, is The United States of America. The Metric Maven has always sided with Oz, sometimes to the point of testing the patience of long-time readers. Keep this in mind, because it’s crucial to what follows.

A new book, Whatever Happened to the Metric System? How America Kept Its Feet, by John Bemelmans Marciano, ostensibly on the failure of metrication in the US, has us here at TheMetricMaven.com in a quandary. If the subject matter matches the title, then we might be expected to have an opinion. Silence might even be misinterpreted. On the other hand, if the book is something else, we could find ourselves in the position of electrical engineers trying to make sense of a seriously bizarre piece of dilettante sociology.

The book certainly starts off at the right point: the early 1980s, when Ronald Reagan gave the coup de grâce to any hope for imminent US metrication, by abolishing the US Metric Board. The Board had been in existence for only seven years, and still represents the sole official attempt to bring US measurement into alignment with the rest of the world. (I can personally attest that it was a time when kids were told by teachers that, ten years out of high school, we would never have to worry about confusing an ounce weight with a fluid ounce again.) But the Board foundered early, for reasons that will not be easily explained to citizens of European democracies. (Long story short: some members of the Board apparently saw their function as more than purely nominal.)

Before exploring this failure, however, Marciano indulges in an extended historical digression: at least twelve of his sixteen chapters. Our first major stop is actually the French Revolution. And I do mean stop: we will be stuck in France from well before the Reign of Terror, and will be hanging around for at least two Napoleons after (numbers I and III, I’m pretty sure — I’ve forgotten if II gets a mention, and frankly it’s not worth checking). The French chapters run from at least three through six and beyond, with chapter two, on the francophile Thomas Jefferson, as a kind of preamble. This makes the French section well over one fourth of the book. Although the book’s title suggests a specific focus on the failure of the US, alone among the nations, to metricate, the bulk of the book takes place elsewhere, and has only tenuous relevance to the US failure. The book seems to be intended more as a capsule history of the metric system. And if this is indeed the intention, then there is a grave problem. To paraphrase Sherlock Holmes, there is a dog that didn’t bark in the night: the complete absence of John Wilkins (1614-1672).

Ten years ago, a book on the history of the metric system might have been excused for not mentioning John Wilkins, and parroting the conventional wisdom that the metric system sprang fully formed, like Athena from the head of Zeus, out of revolutionary France. But it is now known, largely from the research of Pat Naughtin, that the idea of systematized measures, divorced from any artifact, had been around long before: at least one hundred twenty years before the Revolution. In 1668 Wilkins published An Essay Towards a Real Character, and a Philosophical Language, which included a proposal for an integrated system of linear, volume, and weight measures. It was not an isolated effort. William Brouncker, and the far better known Christian Huygens, collaborated. But the man who came up with the technological device that made the system possible, the “seconds pendulum,” may have been Christopher Wren, not primarily a scientist (or “natural philosopher”), but the architect of London’s St Paul’s Cathedral. Wilkins’ book was widely read well into the 1800s, and the units for length, volume, and weight it advocated were remarkably close to those later arrived at by the French by more dubious means.

Marciano is aware of such devices as the seconds pendulum, and of Jefferson’s disgust at the French rejection of them, which makes his silence on John Wilkins even more puzzling. The same silence, incidentally, is found in Marcus du Sautoy’s recent BBC documentary, Precision: The Measure of All Things. Du Sautoy also makes the astonishing claim that the French insistence on basing the meter on the Paris meridian was somehow an act of cooperative internationalism. Marciano doesn’t go this far, and seems to understand that their seven-year exercise in trigonometry was ultimately pointless, but persists in calling this nationalistic reboot or retread of some very old ideas an act of invention. He also discusses problems with the seconds pendulum that were apparent at the time, but which could have been compensated fairly readily. (A seven-year study of the behavior of pendulums in various parts of the world would also have provided a lot of information on the precise shape of the earth.)

The author’s Tilt-A-Whirl approach to history is engaging, his chapters on the French Revolution more fun than a free ride in a tumbrel, but perhaps not by much. It’s actually hard to find much in the book that has anything to do with SI, today’s metric system, or even measurement per se, except by implication — possibly invidious. There are long sections devoted to such things as English spelling reform: Noah Webster’s partially successful efforts to redefine American English; and the completely unsuccessful attempts of such disparate characters as the rather pathetic Melvil Dewey (of Dewey Decimal fame), and Teddy Roosevelt. The efforts of advocates of artificially constructed languages, Esperanto, and its less-known predecessor Volapük, are detailed. One entire chapter is devoted to the development of standard time; and another is on attempts to rationalize the calendar, which continued through the 1920s. Cranky figures take the front row, including extended discussions of perhaps the greatest of nineteenth-century crackpots, Charles Piazzi Smyth, and his obsession with the Great Pyramid. Yet another chapter is given over to a man who, although no crank, is no more than a footnote in metric history: John Quincy Adams and his pointless and unreadable Report on Weights and Measures.

A great deal of the book concerns something that most people today wouldn’t think of as measured at all: money. This is justified on the grounds that “In the late eighteenth century, coinage was not only a part of weights and measures, it was the most vital part, and had been for thousands of years.” This is arguable (although some of us might point out there was an awful lot of measurement-based engineering going on in the ancient world, and when buildings and aqueducts fail, people die). But even granting this, money today is counted rather than measured: a very different thing. Neither SI, nor any of its several predecessors has a monetary unit. This doesn’t mean, however, that we aren’t going to be spending some time in Bretton Woods.

Eccentrics and guru-like figures continue to dominate in the “contemporary” section, from about 1970 onward (essentially just the last three chapters). Two of these are introduced in chapter one: Stewart Brand, described as a “libertarian prototechie,” and Tom Wolfe, a “literary icon in a white suit.” Brand, editor of The Whole Earth Catalog in its myriad forms (all of them aging ungracefully, or thankfully forgotten) specialized in demagoguery by using metric system and nuclear power in the same sentence on all occasions. Wolfe then apparently dealt metric a crushing blow when he judged a “Most Beautiful Foot” contest at a party called a “Foot Ball.” Yet another oddity: the editor of the American Journal of Physics (actually a teaching journal) is cited, apparently with approval, for using such units as the “jelly doughnut” (106 joules) in an attempt to make science more understandable. (Last time I looked, the joule was an SI unit, and 106 was the prefix mega-. I like reporting food energy in megajoules, and I’m completely on board with making science understandable. I’m just not sure rebranding the megajoule as a jelly doughnut is the best way to do this.) The book also degenerates into reporting anti-metric t-shirt slogans and schoolyard taunts of the era.

Does the book address any technical issues at all? Very few, but one comes up at least twice, attributed to Tom Wolfe: “NASA had gone to the moon on inches and pounds and had never considered any other system.” Not true, of course. The computers aboard the Apollo spacecraft performed all calculations in metric. Only the displays were in archaic units. Considering the low speed of those early computers, that unit conversion must have been a significant extra computational load. But it is true that NASA was and is hostile to metric.

The author is under the curious impression that NASA learned a lesson from the Mars Climate Orbiter: “America has gone metric where it has been useful to do so. Thankfully, this now includes space travel.” Sorry, but again no. Official policy to the contrary, NASA and its supporting industries are as intransigent as ever. For as long as the Space Shuttle was in service, NASA baulked at any attempt at metrication, on the grounds that the conversion of drawings would have been too expensive. Now the Shuttle is retired, and the US has no manned spacecraft. American astronauts thumb rides on Russian spacecraft. NASA has as near a clean slate as it will ever have. But the contract for Orion, the manned spacecraft intended to replace the Shuttle, was awarded to Lockheed Martin, at least in part because Lockmart specified in its proposal that archaic units would be used whenever possible.

And our poster child for rational, democratic metrication? Australia gets one mention, and only to say that it had found metrication a “relatively straightforward project.” Come to think of it, there is another dog that didn’t bark lurking here. The Australian experience was that metrication costs were so low they were instantly swallowed up in the benefits. Considering how money-oriented this author is, it’s strange he never considers such terms as one-time costs, or ongoing benefits.

The book ends on a weirdly inverted triumphalist note. In fact, the entire book is a kind of celebration of technical and economic eclipse as social triumph. When I picked it up, I had in mind a map of a metric world with one obvious, US-shaped black hole in it, and the question “What happened?” Now that I’ve put the book down, I still have the same question.
