A Metric England?

By The Metric Maven

As it became increasingly clear in the early 1980s that the US would not become metric, a professor of mine stated  “England doesn’t even use the English system—they’ve gone metric.” Of course, I had no idea. I’ve never been to the UK. I assumed that Britain had gone metric because the rest of the world had at that time. Then lingering doubt began to creep into my mind as the decades passed, and I began to believe that Britain had not become metric. It appeared that beer was still sold in pints, and the roads were all in miles. I vaguely heard about the “metric martyrs” and the EU throwing its hands in the air and finally giving up on metric only labeling from the UK. The BBC science programs I watched seemed to have a lot of “English” units, at least I seldom noticed metric ones (although I believe I see more used now).

Like most Americans, I figured they had done the same thing  as we in the US, they offered lip service during the world wide metric conversion, and then sat back, and never changed anything. All I had to do was look North to Canada for an example of a country which still has the Queen on its money, has the roadways all in metric, but almost everything else from cooking to housing construction appears to be in inches, feet and so on. Why would I believe that Great Britain, which had pints and miles everywhere, was metric. I really didn’t think about it much as I have enough problems dealing with the immovable and incorrigible metric object known as the USA. Worse yet, I’d read almost a century of authorities in the UK claiming the UK would become metric when the US did. I would then read US authorities over the same period claiming that we would become metric when the UK did.

Derek Pollard of the UK Metric Association could not help but notice that I saw Australia as an English speaking metric country, but not Great Britain. He took exception with this view and sent proof that UK construction is in metric, which clearly it is. Still, there is that nagging feeling that metric penetration into British society was a millimeter deep. Sure, construction of UK roads is in meters, but then they mark them in miles. Sure houses may be constructed in metric, but the streets are all marked in non-metric units. Beer may come from Belgium, but they sell it in pints. The US, of course, does neither, it’s all Ye Olde English, and when it’s metric, it is immediately converted to Ye Olde English and hidden away.

Derek must have continued to sense this leftover minor metric skepticism, because it seems to have finally caused him to send me iron clad, and unquestionable proof that the everyday UK of Andy Capp is almost entirely metric. Did Derek get an official letter that certified the UK is metric, have it signed by the Prime Minister, and then notarized by the Queen? No, he send me documents which have far more authority than that. He sent me some of his “junk mail.” He sent me a small paper flyer from a place called Morrisons:

British Beef Meatballs, British Diced Chicken Breasts, British Lamb chops all sold pre-packaged in grams! Meadow Park milk is shown sold in 2 litre plastic containers—not a pottle—that.

Included in Derek’s letter is a 32 page flyer from B&Q Warehouse which looks like a UK version of Home Depot–but, from a measurement perspective, that’s where the similarity ends. Want to purchase a door for your house?  Well look no further than B&Q for doors specified in millimetres:

Unfortunately,  as Derek points out, the strange numbers (1981 x 762 mm) show that they are probably converted from non-metric sizes as they are not not nice round integers. This is a hinderance to thinking metric when building, and realizing its maximum benefit.

There is paint sold in 2.5 liter cans, others just tell you the price per litre. There are 333 x 333 mm porcelain floor tiles. Ice melt is sold in 2 kg bags. Wild Bird seed in 12.75 kg bags—the British must feed their birds well. Everywhere one looks in these junk mail flyers, there is an almost complete absence of anything non-metric. There are no side by side sizes, one in metric and the other in Imperial—it’s all metric! Very simple. I did find my nemesis, the centimeter, but only in one tiny section for door mats:

Centimeters — Appropriately Treated Like A Door Mat (click to enlarge)

Indeed, that centimeters would be used for door mats, and they were only a pound each, actually made sense—metaphorically. The other centibad was found in the Morrison’s food flyer. But this may not be the fault of the British merchants—it looks to be the fault of the French! A seventy five centilitre bottle of wine! Here is one of the few times I can thumb my nose and say I want a proper, American, 750 mL bottle of wine–you know a fifth. For the first time ever, I can feel sanctimonious.

French Wine with questionable metric usage

The French are not the people with whom you should discuss how to most effectively use the metric system. Their use has pre-metric vestiges of the prefix cluster around unity.

Derek pointed out that a radiator is rated in BTU’s on one page, and on the other they have one which is 2kw, which should be 2 kW of course—but my heavens, I don’t know that I’ve ever seen anything with kW on it in the US like this. I’m baffled by the fact that the flyers often don’t have spaces between the numbers and units, as evidenced below:

BTU?—perhaps that’s why it’s on sale?

When I look at these flyers, it makes me rather envious, and think that if the US was this metric, I would just stop blogging and go outside to play. It then struck me just how frustrating it must be to have metric all around, but not on the roads, or in the pubs. It would be a constant non-metric reminder one would see everyday when they left their residence. It would also seem more and more absurd as time goes by. I’m extremely envious of Derek’s junk mail, but it’s clear the UKMA has plenty of non-metric fires to deal with before Britain becomes completely metric. Here in the US?—well, my junk mail is metricless.

Postscript:

My friend Pierre keeps me informed on all matters culinary with an emphasis on metric versus Olde English. He sent me a graphic of a deep fryer with this comment:

Commercial fryers, like what McDonalds uses to make french fries are sold by volume. Like, there are bigger and smaller capacity ones.

Can you guess what unit of measurement one might use to specify them?

They are sold by the pound. That’s right. They are sold by how many pounds of oil they hold. This is a 14lb unit, which I’m sure you knew already by looking at it.

So, next time you are in Safeway …. , pick up a pound of frying oil for me, wouldja?

Here is a link to the fryer about which Pierre so eloquently opines. But there’s more! Pierre also checked out oils he might like me to supply for him, should I feel that generous, and indeed you can note that one will purchase a 35 lb box of oil, and not one using Olde English volume measures:

And just in case you think the labeling has liters on it. Here is a close-up of the bottom label:

So, should any of our friends from the UK decide they want home-made fish and chips on a visit to the U.S., and want to do it themselves, you now know the proper US units to use when using a fryer here.

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.

A Kilotonne is How Much in Metric?

By The Metric Maven

Bulldog Edition

When I was in college, I studied Electrical Engineering. I was told many times that one was no longer to use concatenations of metric prefixes, this was considered very bad practice. What this meant was that one should not use two metric prefixes concurrently to designate values. At that time there were capacitors which were marked micro-micro Farad (μμF). Micro is 10-6 so two of them together would 10-6 *10-6 or 10-12. There is a perfectly good metric prefix called pico to describe this small amount of capacitance. The slang term is puff. So these μμF capacitors should be described as picofarad pF capacitors. This made perfect sense to me. I was surprised that such an ad hoc nomenclature would make it into engineering or be tolerated. When I took my first job, we used a device called a directional coupler to calibrate the power level of measurements. The coupling factor for the directional coupler was shown on a graph which was on an attached metal plate. The coupling was different at different frequencies and the graph was used for correction. The frequency axis of the graph said KiloMegaCycles. I knew this designation was from a long time back as cycles per second had been called Hertz for decades. I found this antique item to be a source of humor for me.  Who on earth would write a frequency in Gigahertz (GHz) [109] as (KMHz) [103 *106 = 109]. How on earth did that make sense? What I didn’t realize was that the US “do your own thing” anarchy of weights and measures allows, and seemingly promotes this type of designation.

Imperial and US Olde English unit usage have been retained in the metric system, and have never been purged as they should have been. I’ve spent considerable time expressing my views about the centimeter as a pseudo-inch, (and have condemned the entire prefix cluster around unity), but there is a much more sinister and in-your-face Imperial/US Olde English holdout in the metric system. It is the tonne. The fact that there is an extra n and e should make one think Ye Olde English metric. The designation tonne is actually an approved usage!  The tonne is properly called the Megagram or 1,000,000 grams, but when used in a completely feral manner they are known as metric tons—no extra n or e, just pigfish. So what is a metric ton? Well it’s 1000 kilograms, or 1 kilokilogram (KKg). It turns out that 1 kilokilogram is close to a short ton (0.907 kilokilograms). A ton is probably derived from a tun which was the weight of a barrel of wine. So why was it so important to taint the metric system with an unnecessary non-metric-metric unit? Had someone been drinking? Worse yet the metric ton is just another way of writing kilokilogram and pretending it isn’t poor usage. If I wrote something has a mass of 97 kilokilograms I’ll bet most pro-metric people would wrinkle their nose and pitch a small fit, but If I said 97 tonnes or even 97 metric tons, well, only the tinkling of ice in glasses around the metric table would be audible. How about K2g for metric ton?—I’ll bet that wouldn’t go over well either. So why is tonne or metric ton acceptable in polite company?

This blog was originally to be about Naughtin’s Laws and the press. I was curious about how “professional”  people talk about large quantities. Well, it turns out that there are many varied and mangled ways that this is done by journalistic denizens of the only country which embraces US Olde English Units. I was curious about the amount of metals produced world-wide, and found a slide presentation with this table:

When my mind encountered the word kilotonnes, it seized up for a moment and I experienced metric vertigo. Kilotonnes!!!  So in other words the amount of metal is being described is in terms of kilokilokilograms or KKKg! That sounds rather ominous—perhaps K3g would be better? Let’s see what would that be in non-pig-Latin metric? Oh, it would be simply Gigagrams. This is not to be confused with Gt which is proper pig-Latin metric for Gigatonne or in improper pig-Latin metric is K5g . The source of this table will remain anonymous. There is no need to single out this person, he never chose to be in the spotlight. But news items which are written by “Journalists” for the public, well, I’m less inclined to invoke a Metric Maven Client privilege. Lest you think this usage is uncommon, the article Great Balls of Fire in New Scientist on 2013-06-29 (page 42) describes the explosive impact of meteors in megatonnes and kilotonnes.  Here are some values in terms of metric tons I randomly found on the web using a google search:

  • Mining operations in Amapa, where Anglo American produced 6.1 million metric tons of iron ore in 2012
  • According to Philips estimates, using the LED replacement could also eliminate 11 million metric tons of carbon emissions annually, or the equivalent of removing over 2 million cars from the road.
  • This clean solar generation plant will displace the equivalent of approximately 54,000 metric tons of carbon dioxide (CO2) per year, which is equal to the amount that roughly 2.2 million trees would displace annually
  • “The ground fish fleet is a huge contributor to local port economies,” he said. “In my district alone, on any given year, you will have a dozen trawlers that contribute 10,000 metric tons of fish and that represents about $20 million worth of product,” he said.
  • The Wikipedia article referenced below indicates that the Earth has around 40,000 Gt of carbon in the hydrosphere, biosphere and atmosphere
  • More than 2,000 farmers in six communities in the Northern Region will benefit from a 500 metric ton certified warehouse for grain storage at Datoyili, in Tamale.
  • From July-February 2012-13 about 5,590,775 metric tons of cement worth US$ 376.85 million exported as compared to 5,589,372 metric tons valuing US$ 303.71 million of corresponding period of last year.

Do you really have any idea of the comparative magnitudes offered in these news stories? I would bet not. Let’s try to get a handle on these values using Naughtin’s Laws (mostly) and Metric Prefixes.

There is no excuse for Americans not to have an idea of the relative magnitudes of Mega, Giga and Tera. Computer disk drives were in Megabytes, then as they became larger they came in Gigabytes, and now one can buy external hard drives of 1-2 Terabytes without a problem. Peta–well, that’s way big, but one can look it up online without a problem if needed.

The presentation of quantities using metric tons only obfuscates a person’s ability to immediately compare them. It also in many cases can serve to obscure the decimal nature of metric values and money. For instance here is the pricing of copper in one article:

  • Benchmark copper on the London Metal Exchange (LME) hit a session low of $7,439 a metric ton (1.1023 tons), its weakest since August 21, and closed at $7,465 a metric ton…

We note that the price is given in metric tons, and then they provide a conversion factor for US Olde English short tons. Let’s see, copper costs $7,439 per metric ton; how could we possibly compute the price of other quantities?  I have an idea, perhaps actually using the metric system might help?  How about $7,439 per/megagram, or $7.43 per kilogram, or 74 cents per gram. Look ma!—no calculator! The metric ton designation really screws up the simplicity of decimals, which is one of the reasons metric was adopted internationally in the first place. Seriously, the metric ton is just a tonne of problems, it should have never been accepted as a legitimate usage in the metric system. It only serves to obscure, and that means that for unscrupulous persons, it’s used for dishonest purposes. It’s not a metric ton, it’s a Megagram! Members of the press—learn to count!—by using the metric system!
