Measuring Tip
Dutch-process and natural cocoa powder have similar densities but behave differently in recipes. They are not interchangeable when leavening is involved.
Understanding the Units
What is an Ounce?
An ounce (oz) is a US customary unit of weight equal to 28.3495 grams or 1/16 of a pound. In cooking, "ounces" refers to weight (avoirdupois ounces), not fluid ounces which measure volume.
What is a Cup?
There are three cup standards used worldwide. The US cup (236.588 ml) is used in American recipes. The metric cup (250 ml) is standard in Australia, New Zealand, and some parts of Asia. The imperial cup (284.131 ml) appears in older British and Canadian recipes. A metric cup holds about 5.7% more than a US cup, while an imperial cup holds about 20% more. Using the wrong standard can noticeably affect a recipe.

Close, but not exactly. The ounces to cups conversion for cocoa powder may vary slightly between brands depending on moisture content and how the ingredient is measured.
The same weight of different ingredients fills different volumes because each ingredient has a different density. An ounce of cocoa powder fills a different number of cups than an ounce of a lighter or heavier ingredient. That is why this converter needs to know which ingredient you are measuring.
