Convert Cups to Grams: Unsalted Butter
Convert cups of unsalted butter to grams with this complete reference table. 1 cup of unsalted butter = 227g (USDA FoodData Central, spooned-and-leveled method). Use the table below for fractions from 1/8 cup up to 4 cups. For precision baking, weight measurements in grams are always more reliable than volume measurements in cups, because unsalted butter density can vary by measuring technique.

|---|---|
| 1/8 cup | 28.4g |
| 1/4 cup | 56.8g |
| 1/3 cup | 75.7g |

Based on USDA FoodData Central data (1 US cup = 240ml = 16 tablespoons = 48 teaspoons). Note: Butter is nearly as dense as water when melted (0.946 g/ml). 1 cup solid butter = 227g = 2 sticks US. Softened butter and solid butter weigh the same per cup — measuring by weight is most reliable. Melted butter = slightly less by volume.
About Unsalted Butter Density
The density of unsalted butter determines how much it weighs per unit of volume. At 0.946g/ml, 1 US cup (240ml) of unsalted butter weighs 227g under USDA standard conditions.
Volume measurements can vary by ±10–20% depending on technique (sifted vs. spooned vs. scooped). For consistent baking results, use a kitchen scale with gram measurements whenever possible. The USDA standard (spooned-and-leveled) is the reference point for all values on this page.
