How many grams are in a cup?

For water, 1 US cup is about 236.588 grams. Other ingredients vary because density changes the weight.

How do I convert cups to grams?

Multiply cups by 236.588 for water. Use ingredient-specific conversion charts when the ingredient is not water.

Why do cups to grams values change by ingredient?

A cup measures volume, while grams measure weight. Different ingredients pack differently, so the same cup can weigh more or less.

Calculation: g = cups × 236.588

Conversion Formula

g = cups × 236.588

Use the formula exactly as shown to convert between cups and grams on a water-equivalent basis.

This page uses US cups and a water-equivalent assumption. Ingredient weights vary, so flour, sugar, butter, and other ingredients will not match the same gram value.

Reverse

cups = g × 0.004227

If you need the reverse direction, use the paired converter and keep the same water-based assumption.
