Cups to grams

Estimated grams120 g

1 cup(s) of all-purpose flour.

Grams per cup120 g

Ingredient density changes the cup-to-gram conversion.

Why ingredient matters

Cups measure volume, while grams measure weight. Flour, sugar, butter, oats, rice, and liquids have different densities, so the calculator uses a common kitchen estimate for the selected ingredient.

Formula

Cups to grams formula

Grams = cups x grams per cup for the selected ingredient

Cups measure volume and grams measure weight, so ingredient density matters.

How to use

Steps

  1. Enter the number of cups.
  2. Choose the ingredient.
  3. Read the estimated grams.
  4. Use a kitchen scale for precise baking when possible.

Calculator use

Best for

  • Quick estimated grams from cups and ingredient.
  • Quick everyday math with the result and formula in one place.
  • Shopping, date, time, unit, school, or household comparisons.
  • A fast check before moving the numbers into a spreadsheet.

Before relying on it

Check first

  • Entering cups and ingredient from different time periods or scenarios.
  • Mixing units, dates, or original values across the same calculation.
  • Rounding early and then using the rounded number in another step.
  • Copying a result without checking whether the inputs match the real-world question.

FAQ

Common questions

How many grams are in a cup?

It depends on the ingredient. One cup of flour is about 120 grams, while one cup of granulated sugar is about 200 grams.

Why do cups to grams vary?

Cups measure volume and grams measure weight. Different ingredients have different densities.

Is this accurate enough for baking?

It is useful for estimates, but a kitchen scale is better for precise baking.
