Convert Cups of Flour to Cups of Sugar

Whether you need to express a value in cup sugar instead of cup flour, this guide walks you through the exact steps. Cooking conversions bridge volume and weight, which matters because ingredients like flour and sugar have different densities even when measured in the same cup.

One cups of flour equals approximately 0.625 cup sugar. This means you can multiply any cup flour value by 0.625 to get the equivalent in cup sugar.
