Short form is used in English only and was reluctantly adopted outside of the US since the 'mericans weren’t going to budge. Any science done in other languages uses the more logical form. I’ve done it myself in 3 of them. And it’s weird how I fluently translate between American billion and international milliard or American trillion and international billion. But I’m sure there is going to be a rocket blown up over this at some point.

Why more logical? Billion, prefix bi for 2 is million squared. Trillion, prefix tri for 3 is million cubed. Septillion, prefix sep for 7 is? Honestly, though, at the end of the day it doesn’t matter that much. It’s just grating that were being yanked backwards. However slightly. And yes, that pun was intentional.

Sure, the US didn’t come up with the imperial measuring system but everyone else has moved on. Miles were used by the Romans but were they the same miles? Everyone had their own foot… the story about Napoleon being short was simply that he was measured in French feet and they were longer than English feet so he amounted to fewer of them. I guess it’s slightly better now that there is only one set* of archaic pre-enlightenment units in play :shrug:

*having said all that, some of the US measurements don’t quite coincide with the UK ones but I can’t remember any if those details. But it’ll probably kill a other rocket too.

PS I dare you to look up the Swedish mile.
