Cups to Grams Cocoa Converter

Estimate the grams of unsweetened cocoa powder in a measured number of cups. The tool also shows kilograms and the corresponding volume, making it easier to adapt a volume-based baking recipe to a scale. It uses a named household-weight reference rather than treating cocoa like water.

How to use this tool

1. Choose the ingredient state that matches what you will actually measure.
2. Select a US customary cup or a 250 mL metric cup.
3. Enter the number of cups as a decimal, such as 0.75 for three quarters.
4. Read the estimated mass and use the reference table to check other quantities.

Formula

grams = cups × reference grams per US cup × selected cup mL ÷ 236.5882365

The metric option assumes the same bulk density as the reference US cup. It is a proportional estimate, not a separate laboratory measurement. Zero cups gives zero mass.

Example

For 0.75 US cup of unsweetened cocoa powder, the reference gives 0.75 × 86 = 64.5 g, or 0.0645 kg. Its volume is about 177.4412 mL. A 250 mL cup is larger, so selecting the metric option changes the mass even when the entered cup count stays the same.

Reference and scope

USDA’s 2002 table lists 86 grams for one cup of unsweetened cocoa powder. This estimate is for the powder, not drinking chocolate, sweetened cocoa mix, melted chocolate or prepared hot cocoa. Brand, moisture and how tightly powder settles in the cup affect the actual mass. A recipe’s own gram measurement is usually the most useful target.
