As if US units were not complicated enough, you might appreciate knowing about the mess with with the kitchen and laboratory ounces.
With U.S. kitchen measures, 1 ounce says 30 mL and 8 ounces says 240 mL on a measuring cup, That's the conversion factor according to FDA. For laboratory work, however, NIST defines the cup as 236.6 <236.5882365> mL. Similarly with conversions from mass ounces: In recipes (FDA) it is 30 g whereas in a lab work it is 28 g. But we landed on the moon, right? It cannot be that bad ☺ As to the scales vs. containers, continental Europe was always mass measuring, as said. The US - the story that has been said on this forum before - discarded scales for cups on the trip across the continent (go west, young man, go west). Cups (containers) were much lighter. Stan J.
