Grams to Cups: Cocoa Powder
If your recipe is written in cups but your scale reads grams — or the other way round — this page solves the conversion for cocoa powder. One cup of cocoa powder weighs about 85 grams, which works out to a density of 0.36 g/ml. From there, half a cup is roughly 43 g, a quarter cup about 21 g, and one tablespoon about 5 g.
Converting between weight and volume depends on density, and density is specific to each ingredient: a cup of cocoa powder does not weigh the same as a cup of flour or sugar. That is why this tool uses the measured density of cocoa powder, taken from the USDA FoodData Central database, rather than a one-size-fits-all figure.

How to measure cocoa powder accurately
How you fill the cup matters a lot with cocoa powder. Spoon it into the cup and level the top with the back of a knife. If you scoop the cup straight from the bag you compact the contents and can add up to 20% more weight than the recipe intends — a common reason baked goods turn out dense.
That is why weighing in grams is always more reliable than cups for precise baking. This page gives you the exact equivalence both ways, so you can use whichever method you prefer.
