Nitpick: regular kind? That's quite… culture centric.

The only "regular" capacity unit that I know of comes from a deliberate attempt to normalize every units. Namely, the Litre from the metric system.

It's not my fault that one of the units is just the name of the other unit with a modifier. It's not like "gallon" is shorthand for something longer and more formal.

Hint: when an Englishman walks into a pub, he doesn't order an 'imperial pint' of beer...

imperial gallon & US gallon?

Or maybe more interesting but historical "ale gallon" and "wine gallon".
