Convert cups to grams

1 cup = 236.6 ml. In grams it depends on the ingredient: 1 cup flour ≈ 125 g, 1 cup sugar ≈ 200 g, 1 cup butter ≈ 227 g.

A cup measures volume, not weight. That's why a cup of flour and a cup of sugar weigh very different amounts. Paste your recipe below and every line is converted using the right weight for that ingredient.

How to measure a cup

The chart assumes the ingredient is spooned into the cup and levelled with a knife. Scooping the cup straight into the flour bag packs it down and can add 20–30 % more flour. That's why weighing with a kitchen scale gives more consistent results.

Not every cup is the same

US recipes use a cup of 236.6 ml. Australia, New Zealand and Canada mostly use a metric cup of 250 ml. The difference is about 6 % and doesn't matter for most recipes. See cups to ml for both.
