Formula and Step-by-Step
- Start with 17.28 ounces of butter
- Convert ounces to grams: 17.28 × 28.35 = 489.88g
- 1 cup of butter = 227g
- 489.88g ÷ 227g/cup = 2.16 cups
The same formula works for any amount. Multiply (or divide) by the density, then convert units as needed.
Measuring Tip
Softened butter and melted butter measure differently by volume. Melted butter settles with no air pockets, giving a slightly higher weight per cup.
