Formula notes
cups = grams / (grams per cup of that ingredient). All-purpose flour ≈ 120–125 g/cup; granulated sugar ≈ 200 g/cup; water ≈ 236.6 g/cup.
Worked examples
- Example: 200 g of granulated sugar is about 1 cup, while 200 g of flour is closer to 1.6 cups.
- If flour is modelled at 125 g per US cup, 300 g is about 2.4 cups; the same 300 g of granulated sugar occupies a different number of cups.
How to use it
- Enter the weight in grams.
- Select the ingredient for the right density.
- Read the cup equivalent for your recipe.
Frequently asked questions
Why does the ingredient matter?
Cups measure volume; grams measure mass. Only the ingredient's density links them.
Why is my flour conversion off?
Scooping packs flour differently; spooned-and-leveled flour is about 120 g/cup.
Limits and interpretation
- Mass-to-volume conversion requires an ingredient-specific bulk density that changes with brand, moisture, milling, and preparation.
- Scooping, sifting, spooning, levelling, and packing can materially change the mass held by one cup.
