How Much Is 8 Ounces of Butter in Cups?
Converting 8 ounces of butter to cups gives 1.00 cup. First convert to grams (8 oz = 226.80g), then divide by the density of butter (227g per cup). Each ingredient fills a different volume at the same weight.
Formula and Step-by-Step
- Start with 8 ounces of butter
- Convert ounces to grams: 8 × 28.35 = 226.80g
- 1 cup of butter = 227g
- 226.80g ÷ 227g/cup = 1.00 cup
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.
