About this calculator

This grams to cups converter translates ingredient weights into cup measures using per-ingredient densities.

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

  1. Example: 200 g of granulated sugar is about 1 cup, while 200 g of flour is closer to 1.6 cups.
  2. 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

  1. Enter the weight in grams.
  2. Select the ingredient for the right density.
  3. 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.
