Butter: Cups to Grams
One US cup of butter is about 227 g (fats & liquids); a tablespoon is about 14.2 g and 100 g is about 0.441 cups. Convert any amount below.
Reference weight: US stick convention. Source checked 14 August 2026; cup-to-weight results remain approximate because packing and product density vary.
Weight uses butter's real density. Volume↔volume and weight↔weight are exact for any ingredient; cup→gram uses a cited reference weight (packing and cup size vary by ±5%).
Note: 1 cup = 2 sticks = 8 oz; 1 stick = ½ cup = 113 g. Butter is sold by weight, so this is exact by convention.
Butter measurement basis
Butter sticks, tablespoons and grams without hidden rounding
This calculator uses 227 g per US cup. USDA FoodData Central's unsalted-butter record (FDC 173430) separately lists 227 g per cup, 113 g per stick and 14.2 g per tablespoon. Those household weights are rounded, so multiplying the listed stick or tablespoon value does not have to reproduce 227 g exactly.
| Recipe amount | Tablespoons | Result from 227 g/cup | Stick shorthand |
|---|---|---|---|
| ¼ US cup | 4 tbsp | 56.8 g | About ½ stick |
| ½ US cup | 8 tbsp | 113.5 g | About 1 stick (USDA lists 113 g) |
| ¾ US cup | 12 tbsp | 170.3 g | About 1½ sticks |
| 1 US cup | 16 tbsp | 227 g | About 2 sticks |
How to use this page
- If the recipe is written in sticks, use the net weight printed on the actual wrapper when it differs from the shorthand above.
- Cup and spoon results here use US customary volume. A 250 ml metric cup is a separate option in the converter.
Boundary: The USDA reference is for unsalted butter. Light butter, whipped butter, spreadable blends and tubs are different products and should not inherit this cup weight.

Why weigh butter instead of measuring cups?
A cup measures volume, but recipes really care about how much butter you add by weight. One US cup of butter is taken as 227 g here, cited from US stick convention, and every conversion on this page routes through that figure. Volume-to-volume and weight-to-weight steps are exact, but the cup→gram crossing depends on product form and how the butter is packed, so a kitchen scale is the reliable way to hit the same result every time.

Is the cup-to-gram figure for butter exact?
