Oh whoopee, mensuration. This is so sad. When I looked for the title photo I at one point searched Flickr for "Meter" and up came a lot of pictures of electric meters, water meters, voltage meters, decibel meters and whatever. Other searches turned up a protester with a sign saying "Metric Now - cooking with imperial units sucks!". I guess cooking and carpentry might be the last to change, but the US and its businesses have changed a lot without announcing it. But a little backstory is perhaps warranted, and, for starts, Imperial Units and Customary US Units overlap a lot, but aren't identical, at least historically. So let's start.

When I was a wee lad in coastal California there were 2 systems of measurement, feet, inches, yards, miles and miles per hour, or, alternatively, fathoms, nautical miles, and knots, but never knots per hour which is landlubber speak. By junior high (late fifties) they introduced those of us in science class to the metric system, which was cool, in that it scaled up by factors of ten, but lacked anything roughly the size of a foot. There was, at the time, some pressure to convert over, like the rest of the world, but mucho resistance. It was probably coming someday so one needed a rough idea of size, 2.54 centimeters per inch, 39.4 inches per meter. 1.6 kilometers per mile (.6 miles per kilometer), and 2.2 pounds per kilo(gram). By the mid sixties, of course, everybody knew a kilo was 2.2 pounds, but that wasn't really about science.

By high school, miles and all that was for carpentry, cars and track. We ran yards, 100, 440 (1/4 mile), and 880 (1/2 mile), and jumps and vaults and such was feet and inches. But science now had 2 systems. Chemistry was cgs (centimeter, gram, second), while physics was mks (meter, kilogram, seconds). Chemistry volumes were mililiters or cubic centimeters which conveniently enough were related in that a cc of water at standard temperature and pressure took up one mililiter. Never really messed with volumes much in physics, but presumably liters was the thing. Nobody, I mean nobody would try to do physics in pounds, feet, and inches because it was just too crazy, nobody except engineers. You see, there was the pound problem. A pound of butter weighed a pound, 5 pounds of flour weighed 5 pounds, and that was just completely wrong. WEIGHT IS A FORCE. Metric forces are in Newtons, a kilogram-meter per second squared. If a pound was a weight, then what the hell was the mass, the equivalent of the Kilogram? Well, it turns out that it was something called a slug that nobody had ever heard of until they ran into the pound problem. It is a mass, equal to the mass that would accelerate at 1 foot per second squared when a force of one pound acts on it . Whaaa? Can't visualize that at all, it has no real size. But, it gets better.

Starting in 1954 they began redefining everything, eventually leading to something called the SI units. This "International System of Units" is basically metric and is the international standard. For grins you should check out the Wiki on it, at least the charts and tables (you won't find the pound, yard or any of that there, btw).
https://en.wikipedia.org/wiki/International_System_of_Units#:~:text=The%...(cd%2C%20luminous%20intensity) That doesn't mean that pounds and ounces ceased to exist, however, but, they did get messed with. They didn't really tell everybody about it, or make it some kind of big deal, but since 1959, by treaty (International Yard and Pound Agreement), the pound has not been a unit of weight (force). Instead, it has been a unit of mass equal to 0.45359237 kilograms. Huh? This was passed into law in the UK in 1963. No law was required in the US since, though often violated, abrogated, or ignored, treaties are automatically the law of the land in the US. So why does a pound of butter still weigh a pound, you may ask? Well, concomitant with the above they invented something called the pound-force Remember that weird-assed definition of the slug? Uh, huh, just the opposite. A pound-force (lbf) is a force equal to the weight of a one pound mass under standard gravity. Of course, that's no big deal because who cares about the pound, right? In fact, the US Metric Conversion Act of 1975 declared the metric system to be the "preferred system of weights and measures" within the US, but did not mandate it, so good old Imperial/Conventional US measurements are still the norm, or are they? For some time now, new US cars contain a lot of metric sized nuts and bolts, bicycles too, and engines are in liters. However, the US is still exceptional using mostly non-metric values for commercial transactions and products.

Our non-metric eccentricity exceptionalism is not without its risks and costs. In 1999, NASA's Mars Climate Orbiter did a faceplant on Mars instead of orbiting it. NASA, science oriented from the word go worked in SI (metric) units, as did JPL, a long-time major subcontractor which was in charge of navigating the thing. Lockheed-Martin, a long-time defense contractor who built the thing, worked principally in dollars US units and therefore provided the thrust data in "good ol merkin units". Needless to say, it did not go where it should have.

This is allegedly the anniversary of a possible date upon which a guy who allegedly never really died died. Given the lack of any known actual fixed date for the death of the non-dead I'm just gonna leave it at that.
