Baking
Cup-to-Gram Converter
Recipes lie. A 'cup of flour' is anywhere from 120g to 160g depending on who measured. This calculator uses standard baking weights so you scale precisely.
Pick an ingredient and amount.
Why weights beat volumes
A loosely-scooped cup of flour can be 30g lighter than a packed one — that's the difference between a cake and a brick. Pros use grams. So should you, for anything where precision matters (bread, macarons, gluten-free).
FAQ
Whose weights are these? +
Industry standard baking weights — King Arthur, Cook's Illustrated, and Serious Eats all use these or very close to them.
Why don't all flours weigh the same? +
All-purpose, bread, cake, whole wheat — different protein and grain content mean different densities. Pick the right one in the dropdown.
What about liquids? +
Water-based liquids (milk, juice) are basically 1 cup = 240g. Oil, syrup, and honey have their own entries.
