Frequently asked questions
How many cups is 120 grams of flour?
Using the listed all-purpose flour reference of 120 grams per US cup, 120 grams is approximately 1 US cup. Measuring technique and flour brand can change the real weight.
Why do grams-to-cups results depend on the ingredient?
Grams measure mass while cups measure volume. Flour, sugar, butter and milk pack different amounts of mass into the same cup, so a reliable estimate must identify the ingredient.
Which cup does this calculator use?
It uses a US cooking cup. The ingredient weights are recipe references rather than a claim that every physical cup contains exactly the same mass.
