How this conversion is calculated

Volume-to-weight conversions are only as good as the density behind them. We treat mayonnaise as 220 g per US customary cup, which works out to 0.930 g/ml. From there:

  1. Your grams figure is converted into millilitres or grams using standard unit sizes (g = 1 g).
  2. The density above bridges volume and weight in whichever direction you need.
  3. The result is rounded the way a cook would round it — to the nearest gram, or to a usable fraction such as 1/2 cups.

Measuring mayonnaise accurately

Emulsified oil holds air, so mayo is lighter per cup than most sauces.

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.
