yes - for example a US fluid Oz is different from everywhere else, as is a cup, a pint, a Venti (twenty what?) and many of the units used in cooking - using American recipes without translation can produce crap - Imperial fluid ounces are totally different largely due tax politics of the 1700/1800s

Venti is not a US Customary Unit.

No but it is one used in commerce ....

Customer: Venti? is that twenty in Italian?

SB Barista: yes

C: twenty what?

SBB: fluid ounces

C: can't be that, they use metric in Italy, must be litres or millilitres

SBB: litres

(at least that's what they usually answer when I try it)
