You’ve Been Measuring 1 Cup Wrong (Maybe) Think 1 cup is the same everywhere? Not quite. In the modern UK, 1 cup is typically taken as 250 mL just like in Australia and other metric countries. But in the US, it’s around 240 mL, and older UK recipes might mean 284 mL! So depending on where your recipe comes from, your ‘1 cup’ could pour very differently. #facts #learning #history #mildlyinfuriating #science #reddit | vt.physics
