What This Calculator Does
The Cups to Grams Converter turns volume measurements into weight using the density of your ingredient. Because a cup of flour weighs far less than a cup of sugar, ingredient-aware conversion is essential for reliable baking.
How It Works
Weight equals volume times density, so grams = cups x grams-per-cup. Common reference values are built into the tips, letting you switch ingredients without leaving the page.
Example
Two cups of all-purpose flour at 120 g/cup equals 240 grams. The same two cups of granulated sugar at 200 g/cup equals 400 grams.
Formula
Grams = Cups × Grams per CupWeight equals volume times ingredient density.
Reading the Results
Grams
The ingredient weight equivalent of your cup measurement, based on the density value you entered.
Frequently Asked Questions
Why do recipes differ on cups to grams?
Because how flour is scooped changes its density. Standard reference values assume lightly spooned flour, around 120 g per cup.
How many grams is one cup of flour?
All-purpose flour is approximately 120 grams per US cup. Whole-wheat flour runs a bit heavier at about 130 grams.
Is it better to bake by weight?
Yes. Weighing ingredients is far more consistent and reproducible than volume measures, which is why professional recipes use grams.
