Spoon, level, then cook.

A light, level cup gives a different weight from a firmly packed scoop. A kitchen scale helps keep the amount repeatable.

How to measure ingredients

How to convert cocoa powder

Our reference is 84 grams per US reference cup of cocoa powder, unsweetened cocoa, levelled. That works out to about 0.355 grams per millilitre, so cups = grams ÷ 84 and grams = cups × 84 in US customary measures.

For metric and Australian recipes the cup holds 250 ml, so one cup of cocoa powder is about 88.76 grams. Australian tablespoons hold 20 ml rather than 15 ml, which the calculator handles when you pick that system.

Preparation changes the weight

The reference describes cocoa powder as: unsweetened cocoa, levelled. A different form, such as sifted, packed, melted, chopped or cooked, can hold a different weight in the same cup and needs its own reference. When a recipe gives a gram amount, weigh that amount instead of converting.

Brand, moisture and how firmly the cup is filled all move the practical result. Treat the numbers here as recipe equivalents, not laboratory densities.

Where the number comes from

The reference comes from King Arthur Baking ingredient weight chart, which lists 1/2 cup as 42 grams. Published recipe weight, normalised to one reference cup. This site assigns the published cup weight to its adopted US reference cup of 236.5882365 ml; the source itself does not define an exact millilitre cup volume. Checked September 25, 2026.

A few useful answers
