Convert Cups to Grams: Cocoa Powder (unsweetened)
Convert cups of cocoa powder (unsweetened) to grams with this complete reference table. 1 cup of cocoa powder (unsweetened) = 100g (USDA FoodData Central, spooned-and-leveled method). Use the table below for fractions from 1/8 cup up to 4 cups. For precision baking, weight measurements in grams are always more reliable than volume measurements in cups, because cocoa powder (unsweetened) density can vary by measuring technique.

Based on USDA FoodData Central data (1 US cup = 240ml = 16 tablespoons = 48 teaspoons). Note: Unsweetened cocoa powder is very light. 1 cup = 100g (spooned and leveled). Dutch-process and natural cocoa weigh the same. Always sift before using. 1/4 cup cocoa + 1/2 tbsp butter = 1 oz unsweetened chocolate.
About Cocoa Powder (unsweetened) Density
The density of cocoa powder (unsweetened) determines how much it weighs per unit of volume. At 0.417g/ml, 1 US cup (240ml) of cocoa powder (unsweetened) weighs 100g under USDA standard conditions.
Volume measurements can vary by ±10–20% depending on technique (sifted vs. spooned vs. scooped). For consistent baking results, use a kitchen scale with gram measurements whenever possible. The USDA standard (spooned-and-leveled) is the reference point for all values on this page.
