Natural and Dutch-process cocoa may behave differently in recipes, but this page uses one practical unsweetened cocoa powder weight. Follow the recipe's cocoa type even when the gram-to-cup arithmetic is similar.
The converter does not assume that every cup weighs 237 or 250 grams. It uses the documented value for the exact ingredient and state selected.
If a product label or recipe publisher supplies a different gram weight for one cup, follow that recipe-specific value for the closest match to the original testing.
