Comment on Why a ton, and not a megagram?
Treczoks@lemmy.world 1 year agoIf you take the context away: When you learn that in school, it’s pointed out as a mistake if you write 10 000m. You should have converted that into 10km to get a perfect score.
Only if this was explicitly demanded. If the teacher doesn’t, and then claim 10000m is “wrong”, the teacher is wrong.

I think I had a strict maths teacher. But they told us upfront how to convert units and how to do the rounding. So there were no ambiguities.
But I’ve also come to the conclusion that humans can handle numbers up to the ten or hundred thousands as well. We mostly do that instead of converting past kilo. And even textbooks say the sun is on average 150 million kilometers away.
