      Americans will NEVER switch to SI (much to my dismay).. Here's why:

      • Football players' union would demand a proportional increase in salary for the extra distance
      • Football stadiums are too short to extend to a 100m playing field and still have enough setback behind the end zones to comply with OSHA safety regulations
      • A quarter pounder sounds bigger than an eighth-kilogrammer, and 100g sounds tiny
      • Americans couldn't comprehend reciprocating fuel mileage (Liters/100km rather than mi/gal)
      • Tons of government software would have to be thrown out and/or rewritten for the switch (wait a minute.... they still use FORTRAN77 for stuff)

      • The Daytona 500 would become the Daytona 804.672, and that number is too big for NASCAR fans to comprehend (it was only recently that they could start having 600 mile races)

      The Carter Administration tried this back in the 1970s. The plan was to gradually ease the U.S. into the metric system; the first step was to put up metric speed limit signs. Patriotic Americans responded warmly by shooting them down. So you could say that the metric system has not caught on very well here, unless you count the increasing popularity of the nine-millimeter bullet. (Paraphrasing Dave Barry.)

      Back in the mid 80's, NPR had a couple of fun articles about the non-celebration of the hundredth anniversary of the US going metric.

      This needed a bit of explaining, of course. It turns out that the US, like most countries, actually has no legally-required system of measurements. There are laws (or more often, regulations) that specific items must be measured with specific units. But there is no overall requirement that all measurements be in the same "system".

      However, the US government has always had an official standards body. It has had various names and acronyms, such as NBS (National Bureau of Standards) or NIST (National Institute of Standards and Technology). It basically manages the regulations that say "If you use unit U, you must use the official definition of U, which is ...."

      So how did the US "go metric" in the 1880's? Well, what the national standards bureau did then was to revise the official definition of all terms of measurement. They've done this many times. At that time, they decided that the best system in use by scientists and engineers was the "metric" system centered in Paris. There were already copies of the metric units in the US, and they were used for calibration. What was done was to make this official, and publish definitions of all the common units as multiples of the metric units.

      These definitions have mostly continued. Thus, the legal definition of an inch is 0.0254 meters. This is not an approximation. It is exact, because it's the official definition of "inch".

      It occurred to me while listening to the NPR articles that what the US has is what we in the computer field would call an "extended metric system". We have all the metric terms, but we also have a whole lot more. This obviously makes the American system more versatile, right?

      So it's really an example of "embrace and extend."
