Cooking measurement converter
A cup of flour and a cup of honey weigh very different amounts, so volume-to-weight conversion has to be ingredient-specific. Pick the ingredient, and scale the recipe for a different number of servings while you are here.

The formula
Grams = millilitres ÷ 236.588 × grams per cup, using the lightly spooned and levelled US cup. Scaling multiplies every quantity by the ratio of servings.
Worked example
2 cups of plain flour is about 240 g. Scaling a recipe from 4 servings to 6 multiplies it by 1.5, giving 360 g.
How to use it
- 1Spoon flour into the cup and level it rather than scooping, which packs it and can add 20%.
- 2For baking, weigh if you possibly can. Volume measures of flour are the main reason the same recipe behaves differently in two kitchens.
- 3Scaling works for most ingredients but not for baking time, tin size, or raising agents in large jumps.
Questions people ask
Why do cup weights differ between sources?
Because the method differs. Sifted flour, spooned flour and scooped flour can vary from 110 g to 150 g a cup. The figures here are the commonly cited spooned-and-levelled values.
Is a cup the same everywhere?
No. A US cup is 237 ml, a metric cup 250 ml, and an Australian tablespoon is 20 ml against 15 ml elsewhere. This uses US measures, which is what most online recipes mean.
