How many ml in a cup?
To work out how many ml there are in a cup, you need to know which cup your recipe/instructions is referencing. The US cup measures 236.59 mL. In comparison, the old imperial UK cup (most commonly referenced in pre-1970s recipes) measures 284.13 mL. The metric cup, referenced in Commonwealth countries and modern UK recipes, measures 250 mL. Here's a chart of how they measure for 1 cup, 1/2 cup, 1/3 cup and 1/4 cup.
