US Finally Switches To International Foot After 60 Year Delay

Change is afoot for the official measuring stick used to size up big places in America. The reason? There are actually two different definitions of the 12-inch measurement known as a foot.

Some land surveyors use what’s known as the U.S. survey foot. Others use the definition that’s more accepted by the broader world: the international foot.

The difference between them is so tiny that you can’t see it with the naked eye on a 12-inch ruler. But over big distances, it matters. So, to reduce the chance for errors and confusion, the federal government has announced it’s finally giving the boot to the survey foot.

The international foot is the smaller one — adding about an eighth of an inch of difference when measuring a mile. That means the United States is 28.3 feet wider when measured using the international foot instead of the survey foot.

The change started in 1959, when the federal government mandated that everyone use the international foot but allowed surveyors to keep to the old U.S. survey foot for a while. That temporary reprieve has lasted 60 years, but it will finally end in 2022, the National Oceanic and Atmospheric Administration and the National Institute of Standards and Technology announced in October.

Surveyors in 40 U.S. states and territories still use the larger U.S. foot. The rest use the smaller international one.

In 1893, the U.S. government defined a foot as 1,200 meters divided by 3,937. Plug those numbers into a calculator and you get 0.3048006 meters. Those last three digits (and it goes on even longer if you want to be technical) are important. Don’t forget them.

In 1933, the international foot was invented. It was simpler: 0.3048 meters, exactly. Those last three digits just get eliminated.

But those digits kept bedeviling engineers. So in 1959, the U.S. government started the international switch and it will finish the job in 2022.

When it finally happens, the U.S. foot will be relegated to history, NIST’s Benham says, “just like a cubit.”

So they came up with the international foot as a mathematical convenience. And then took 3 generations to put it in place. Also, it was probably one of the first efforts to push the country towards metric.

Hey, maybe next week the government will define pi as exactly 3, which would make so much math so much easier.

Not that very many people ever read this far down, but this blog was the creation of Allan Kelly and his friend Vilmar. Vilmar moved on to his own blog some time ago, and Allan ran this place alone until his sudden and unexpected death partway through 2006. We all miss him. A lot. Even though he is gone this site will always still be more than a little bit his. We who are left to carry on the BMEWS tradition owe him a great debt of gratitude, and we hope to be able to pay that back by following his last advice to us all:
  1. Keep a firm grasp of Right and Wrong
  2. Stay involved with government on every level and don't let those bastards get away with a thing
  3. Use every legal means to defend yourself in the event of real internal trouble, and, most importantly:
  4. Keep talking to each other, whether here or elsewhere
It's been a long strange trip without you Skipper, but thanks for pointing us in the right direction and giving us a swift kick in the behind to get us going. Keep lookin' down on us, will ya? Thanks.

Oh, and here's some kind of visitor flag counter thingy. Hey, all the cool blogs have one, so I should too. The Visitors Online thingy up at the top doesn't count anything, but it looks neat. It had better, since I paid actual money for it.
