Why cups to grams depends on the ingredient
Cups measure volume. Grams measure weight. Because ingredients have different densities, 1 cup of flour weighs a different amount than 1 cup of sugar, butter, or cocoa powder.
Use this converter when you want to follow a US recipe with a kitchen scale, convert baking measurements, or make ingredient quantities more precise. For best baking results, weigh in grams whenever you can.
Assumptions
- Densities are approximate. Flour can vary 10–15% by measurement technique.
- Cup volume defaults to US (240 ml). Toggle above for metric (250 ml).
- Results are rounded to a useful precision, not full float-point values.
