You literally pulled up a cherry picked list of where there are discrepancies.

The entire point of this thread from the comment you replied to, is that ‘cup’ is an inexact unit of measurement that varies. My list is providing examples, I’m not seeing the issue here.

Also, would you look at that: almost all of them have converged to US customary or 250mL, which is within the tolerance for error.

Except for Latin America, the UK, most of Asia, parts of Europe, etc. 🙄
