Grams to Cups Converter
Convert grams to cups for common cooking and baking ingredients. Because grams measure weight and cups measure volume, the answer depends on the ingredient.
US = 240 ml, metric = 250 ml.

Why grams to cups is not one-size-fits-all
Grams are a weight measurement. Cups are a volume measurement. There is no single universal grams-to-cups conversion that works for every ingredient — 100 grams of flour, sugar, and butter all take up different amounts of space.
Use the ingredient picker above for the most accurate estimate. For baking, weighing ingredients on a kitchen scale is more accurate than measuring by volume. For a quick reference across many ingredients at once, see the kitchen conversion chart.
When to use grams instead of cups
Use grams when accuracy matters — flour, cocoa powder, powdered sugar, and chopped nuts can be packed loosely or tightly into a cup, which throws off the volume reading.
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.
