Cocoa Powder: Cups to Grams
Quick answer: One US cup of cocoa powder weighs about 85 grams (3 oz), and one tablespoon about 5 g.
US recipes measure cocoa powder in cups; the rest of the world weighs it. Convert any amount in either direction — and measure it the way the chart assumes: spoon and level — cocoa compacts hard in the tin, and scooping can add a third more.

How it works
Cups measure volume and grams measure weight, so the conversion runs through density: cocoa powder packs about 85 g into a US cup (237 ml). Volume is only as accurate as your technique — spoon and level — cocoa compacts hard in the tin, and scooping can add a third more. That variability is exactly why serious baking recipes list grams, and why a $15 kitchen scale upgrades every bake. If your recipe uses metric cups (250 ml), the weights run about 5% higher.
Frequently asked
How many grams are in a cup of cocoa powder?
About 85 grams (3 oz) per US cup, measured properly. A tablespoon is about 5 g.
How many cups is 250 g of cocoa powder?
About 2.94 cups. Divide any gram amount by 85 to get cups — or flip the converter above to grams and it does it for you.
Natural or Dutch-process — same weight?
Same weight per cup (~85 g), but they're not always interchangeable: natural cocoa is acidic and works with baking soda; Dutch-process is neutral and pairs with baking powder.
