#FunFact Just listened to Last Week Tonight and learned that in the US, they use the "unit" "acre feet" for water volumes. And I though I was making fun of this imperial unit BS. They do it all on their own! #SystemeInternationalIlliteracy
@cweickhmann Acre feet...? Isn't acre a surface area unit? How do you do volumes with that one?
@trinsec @cweickhmann yes, an acre-foot is the area of one acre times a depth of one foot:

We didn't do it. Our ancestors did it (actually your European ancestors did imperial units), but now we are stuck with it.
I use metric as much as possible but many in the US just get a blank look on their faces when they hear k/h or m/s instead of mph, for example. So I need to use imperial units sometimes if I communicate to a US audience.

Sometimes I accidentally use celsius instead of fahrenheit when I say something about the temperature and that gets really confusing...
