I think there’s something like 43/500ths of a Bigole Hertz to a regular Hertz; but that’s if you’re using English Bigoles. I think it’s 43.9/500ths for a US Bigole.

I usually just rent from Enterprise. They pick you up!

I’m American and I’ve never seen any other unit used for frequency unless you count adjectives like “daily”.

RPM (revolutions per minute) is an old rotational measure

But the second is the same in both systems so I wouldn’t be surprised if America called revs per second “Hertz”
