How it's calculated
g = cups × k (reverse: cups = g ÷ k)
cups = US cups, g = grams, k = grams per US cup of the chosen ingredient (e.g. flour ≈ 125, sugar ≈ 200).
Common values
| Ingredient | Grams per US cup |
|---|---|
| All-purpose flour | 125 |
| Granulated sugar | 200 |
| Butter | 227 |
| Water | 237 |
Common questions
How many grams of flour are in a cup?
About 125 g for all-purpose flour. Spoon it in and level it off, since packing it can push that to 150 g or more.
Why isn't one cup always the same in grams?
A cup is a volume, and ingredients weigh different amounts for the same volume. Sugar is denser than flour, so a cup of sugar weighs more.
