How to Convert Cups to Millilitres
1 US cup = 240 ml. Multiply cups by 240 to get ml. So 2 cups = 480 ml. UK and Australian cups are slightly larger (250 ml standard); the US cup at 240 ml is the most common in published recipes globally because of US recipe export.
American recipes use cups for liquids and bulk dry ingredients. Converting to ml gives metric kitchens an exact volume. A US cup of milk is 240 ml. A UK cup of stock is 250 ml. The 4% difference rarely matters for savory cooking; precision baking should match the recipe's origin (US recipe = US cup = 240 ml).

Frequently Asked Questions
Is a UK cup the same as a US cup?
Close but not identical. US cup = 240 ml; UK metric cup = 250 ml; UK old (imperial) cup = 284 ml (rare now). The 4% difference between US and UK metric cup rarely matters for most recipes.
Can I use a measuring jug for cups?
Yes if marked. Most measuring jugs show ml/L primarily, sometimes with cup markings. Converting cups to ml first lets you use any volume measuring device. For dry ingredients in cups, weight (grams) is more accurate than volume.
