And not a metric measurement in the carload.

No metric there either.

Actually, the Luna Module's onboard Apollo Guidance Computer (AGC) was programmed and worked entirely in metric units, though it then converted the calculated values to units such as feet per second and nautical miles to display them to the astronauts.

Because they were embarrassed to be associated with that crap. There was clearly a payoff in there somewhere.

The astronauts were recruited from test pilots, who had been trained in, and spent their working lives using, the foot-pound based units. So it was sensible to display values to them in units they were familiar with.

For the many automatic control systems that didn't involve astronauts in the loop, the whole thing was done in metric - and even for the control systems that did involve the astronauts, it was still quicker to do all the mathematics in S.I. units and convert the answers just for display, rather than mess around with ugly units such as slugs and poundals that require extra multiplications by arcane constants at every stage.

But kudos to all the engineers that designed the Apollo systems and made them work so well: despite working in ancient units, and doing most of their engineering calculations with slide rules and mechanical calculating machines, they did a fantastic job. Bravo USA engineers of the 1960s, and bravo USA taxpayers of the 1960s for paying for the program!

Yes. And in the future, an equity based system of education will ensure that such achievements are still attainable. They are currently working on a Eubonics to English app for the Com gear.

John Deere went metric way long years ago. I'm sure a proud capitalist (as am I) can see the reasoning.
