Grams to Cups: Conversion Chart by Ingredient
July 14, 2026
Converting grams to cups sounds simple, but the answer changes with every ingredient — a cup of flour and a cup of sugar weigh very differently. This guide gives you the correct grams to cups values for common baking ingredients, plus a free converter.
Why grams to cups depends on the ingredient
Grams measure weight; cups measure volume. Because ingredients have different densities, there is no single grams to cups number. Flour is light and airy, so it takes more volume to reach 100 g than dense honey does.
