SI units: because 9,192,631,770 is such a round number
Note: The kilogram is technically defined only from the ridiculous lump of metal in a vault in France. The thing with water is the traditional, imprecise definition, but I included it for the sake of explanation (maybe the second’s definition as a fraction of a day should be in there, but ah well.) I used the American spelling of
“meter”, but the quotes (both from Wikipedia) use the official international spelling.
Interestingly, the main complaint with the SI system seems to be that “amount of substance” isn’t a proper physical quantity.
What’s the matter, guys? I thought you liked arbitrary big numbers?
Hmm. I should note, too, that it’s still a far better system than anything else out there, before the powers-that-be force me to use Furlong/Firkin/Fortnight instead.
I want a t-shirt with “Fuck the International Prototype Kilogram”.
