Cup measures are easy but inconsistent — a cup of flour and a cup of honey weigh very differently. This chart gives the gram weight of one cup (and one tablespoon) of the baking ingredients you reach for most.
| Ingredient | 1 cup (g) | 1 tbsp (g) |
|---|---|---|
| All-purpose flour | 120 | 8 |
| Bread flour | 127 | 8 |
| Cake flour | 114 | 7 |
| Whole wheat flour | 120 | 8 |
| Granulated sugar | 200 | 13 |
| Brown sugar (packed) | 220 | 14 |
| Powdered sugar | 120 | 8 |
| Butter | 227 | 14 |
| Honey | 340 | 21 |
| Milk or water | 240 | 15 |
| Cocoa powder | 85 | 5 |
| Rolled oats | 90 | 6 |
Weigh for accuracy. A kitchen scale removes the guesswork — how you scoop flour can swing a cup by 20% or more, which is enough to change a bake.
FAQ
Why doesn’t a single grams-to-cups conversion work for every ingredient? Volume-to-weight conversion depends on an ingredient’s density, so a cup of a dense ingredient like sugar weighs much more than a cup of a light ingredient like flour or cocoa powder, which is why accurate conversion needs to be ingredient-specific.
