I recently got into an argument over how big a cup is. I’d thought that measurement came in only two sizes, Imperial and Metric, so I hit up Wikipedia.
|1 U.S. legal cup||240mL|
|1 U.S. customary cup||236.5882365mL|
|1 Metric cup||250mL|
|1 Imperial cup||284mL|
|1 Canadian customary cup||227.3045mL|
|1 cup in some Latin American countries||200mL|
|1 contemporary Japanese cup||200mL|
|1 historic Japanese cup||180.3906836mL|
… This is why we cannot have nice things.
