Formula and Step-by-Step

(ounces × 28.35g/oz) ÷ 227g/cup = cups

Start with 1 ounce of butter
Convert ounces to grams: 1 × 28.35 = 28.35g
1 cup of butter = 227g
28.35g ÷ 227g/cup = 0.12 cups

The same formula works for any amount. Multiply (or divide) by the density, then convert units as needed.

Measuring Tip

Cold butter straight from the fridge is hardest to measure by volume. Cut it into tablespoon-sized pieces using the wrapper markings for accuracy.
