How this conversion is calculated
Volume-to-weight conversions are only as good as the density behind them. We treat egg whites as 243 g per US customary cup, which works out to 1.027 g/ml. From there:
- Your millilitres figure is converted into millilitres or grams using standard unit sizes (ml = 1 ml).
- The density above bridges volume and weight in whichever direction you need.
- The result is rounded the way a cook would round it — to the nearest gram, or to a usable fraction such as 3/8 cups.
Measuring egg whites accurately
One large egg white is about 33 g. Weighing whites is the only reliable way to scale meringues.
If a recipe matters to you — bread, macarons, anything with a tight hydration or ratio — weigh it. A £10 digital scale removes the single largest source of variation in home baking, and it is faster than washing three measuring cups.
When cups are fine
- Liquids measured in a proper jug, where volume is the honest unit anyway.
- Forgiving savoury cooking: soups, stews, stir-fries, marinades.
- Small amounts of leaveners and spices, as long as you use level spoons.
