The ‘Argument of Twelves’ and the Metric System

The fact that we have 12 inches in a foot isn’t a good reason to reject the metric system. Image from arielrobin on Pixabay.

(Sorry for the long lag between posts. I had some things going on in my life that required my full attention. Things are pretty much back on track. Thanks for your patience.)

Awhile back I was fulfilling my role as a scientist ambassador at the Bradbury Science Museum here in Los Alamos, NM. (This mostly consists of setting up various measurement activities and chatting with visitors about the advantages of the metric system for a couple of hours on the occasional Saturday.)

One day I realized that a man was starting to pace back and forth in front of me. Even though I wasn’t yet done prepping and I sensed this gentleman was about to go on the attack, I went ahead and said, “People are dying in this country because we don’t use the metric system in this country.”

“I don’t believe you,” he replied.

Even the Centers for Disease Control recommends strict use of metric units for liquids. (Pills are measured in grams, or a fraction thereof, already.)

I then handed him the 2016 Top Ten Patient Safety Concerns for Healthcare Organizations report put out by ECRI [Emergency Care Research Institute]. Number seven on the list: “Medication Errors Related to Pounds and Kilograms.” It advocates for only using metric system units (i.e. kilograms for weight) to reduce dosing errors since most medications use weight to determine the correct dose. It’s reason is simple: There are about two pounds in a kilogram. Doctors and nurses are schooled in the metric system but have to bounce back and forth between metric and U.S. customary units to communicate with their American patients. If they mix up the two, they might give the patients half the dose they need (potentially rendering it ineffective) or twice the amount (read overdose).

Using metric system units for medicine has also been recommended by multiple health organizations including the Centers for Disease Control. (See the above image)

The gentleman reviewed the report and since—I assume—he could no longer argue on that particular point, he launched into what I’ve now dubbed “The argument of twelves.”

The Argument of Twelves

The argument goes something like this: If you are working with a group/set of 12s, then your factors are 1, 2, 3, 4, 6, and 12; but if you are working in the metric system, your factors are only 1, 2, 5, and 10.

I consider this to be a specious argument since (and please, but nicely correct me if I’m wrong) we don’t really measure a lot of things by twelves. Sure, a foot has twelve inches and there are twelve months in a year. (Apparently eggs are sold by the dozen—according to the New York Times—because eggs were a penny each and there are 12 pennies in a shilling. Selling eggs by the dozen meant, as a vendor, you didn’t have to make change.) However, there isn’t much else I can think of that comes in twelves except a gross of 144 items (which is 12 multiplied by 12). You can’t really cite time because military/Zulu time uses a 24-hour clock.

If we actually had 12 ounces in a cup and 12 cups to a gallon and 12 ounces in a pound and 12 yards to a mile, then I would understand that counter argument. (In reality, there are 8 ounces in a cup, 16 cups and 128 ounces in gallon, 16 ounces in a pound, and 1,760 yards in a mile…plus 36 inches or 3 feet in a yard and so on.)

But, when it comes to everyday measurement, we really only divide up inches, months, and eggs into twelves. I don’t think that’s enough reason to reject using the metric system.

However, I’ve found after seven years on this project (the anniversary of which was the day before yesterday), if people are threatened by the idea of changing to the metric system—for any number of reasons—they will latch onto whatever immediately comes to mind to reject it.

Around the time that the man was winding down his argument of twelves, some other—more open-minded people—approached me and I turned my attention to them.

I’ve said many times that, when it comes to this issue, there are probably 10-20 percent of people who already love the metric system and there’s about another 10-20 percent who are completely opposed to it.

It’s my plan to focus my attention on the 60 to 80 percent who don’t realize we have a problem in this country and are open to learning about it. Maybe action will eventually occur. That’s my hope. If you want to become more involved, let me know at milebehind@gmail.com.

In a closing note: I realize that some people ascribe a historical and religious meaning to the number 12, but we don’t have to limit the number of members on a jury or the number of apostles due to the metric system so let’s not shoehorn that number into our measurement system unnecessarily.

Plan for another post in September.

Thanks for getting this far,

Lack of U.S. Metric Adoption and International Interest

When I first learned about the historic multiple failures of U.S. metric adoption, I believed only Americans would care about the story. I came to realize that nothing is further from the truth. I suspect that some of that external interest comes from the same reason that people slow down when they pass a car accident: morbid curiosity.

I don’t say that to be mean but I think it’s a human trait that when you see something that you really can’t explain and seems really peculiar you start to wonder what’s going on. That’s pretty much us with regard to metric adoption. People in other countries who realize how far behind we are here must be scratching their heads as to why we still can’t get our act together and go metric like almost every other country has.

The U.K. Connection
One of my early clues that this story was of international interest was when I started my Twitter account and folks from the U.K. and Canada started following me. As I started to think about it, that kind of made sense. After all, the U.S. and U.K have ties that date back more than 200 years. But, it turns out, not only are folks in the U.K. interested in this topic but top visitors to this blog are all former British colonies. That fact becomes visually striking when you look below and notice that in the case of New Zealand and Australia the U.K. flag is still embedded in their current “colors.” That’s less true of Canada, but then their currency is emblazoned with Her Majesty the Queen, so that takes any ambiguity out of the equation.

I tend to think of U.K. and these other top followers as our brothers and sisters because of these joint ties.

I’m also not the only American to notice that we tend to demonstrate our affinity to our U.K. roots in odd ways. Take, for instance, a New York Times article from late last year that mused over our bemusing tendency to incorporate Britishisms into our American speech. Titled “Americans Are Barmy Over Britishisms” it says, in part:

Crikey, Britishisms are everywhere. Call it Anglocreep. Call it annoying. Snippets of British vernacular — “cheers” as a thank you, “brilliant” as an affirmative, “loo” as a bathroom — that were until recently as rare as steak and kidney pie on these shores are cropping up in the daily speech of Americans (particularly, New Yorkers) of the taste-making set who often have no more direct tie to Britain than an affinity for “Downton Abbey.

(http://www.nytimes.com/2012/10/11/fashion/americans-are-barmy-over-britishisms.html?pagewanted=all&_r=0)

Some of this carryover must work both ways since our sibling countries are apparently wondering what the heck we are doing that we’re still behind the curve when it comes to metric adoption. Are the folks in Canada and New Zealand thinking something akin to “If we figured out how to grow up decades ago, what’s going on in the U.S.?”

The French Connection
Interestingly, while I was looking over my statistics for this blog on Friday I saw an unusual number of hits had come from France. A little investigation revealed that a woman writing on American topics, including this week our measurement system, had this to say about this project (translated from French):

If you are passionate about the subject, go to this American blog, A mile behind, denouncing the non-use of the metric system in the United States from all angles (the States are one of the only three countries in the world – with Burma and Liberia to not have standardized the metric system).

(http://www.maathiildee.com/2013/04/04/les-mesures-a-lamericaine-parler-en-inch-fahrenheit-et-)

As this project progresses I’ll have more of a chance to talk to people around the globe. Then I’ll get a much better feel for this interest and not only how we are perceived by those countries to which we have these extended ties but others around the rest of the world.

Want to join my mailing list?
I’m now starting a mailing list so if you would like to be added to learn more about this project outside of this blog, please feel free to send me your email address. I promise that I won’t sell or lend it. If you want to learn more about this project, that’s the least I can do.

Just send an email to milebehind@gmail.com to be added to the distribution.

I also welcome any thoughts or comments you might want to share in the email. I’ll assume that if you wanted them to be public, you’d comment on this post. Therefore, if I decide to share any of your thoughts in any way, I’ll do so in a way that keeps you anonymous. So, if you don’t want me to share at all, probably best not to send comments to me.

Thanks for your interest and I’ll keep moving this project forward.
