Formula and Step-by-Step

teaspoons × 4.73g/tsp ÷ 28.3495g/oz = ounces

Start with 400 teaspoons of butter
1 teaspoon of butter = 4.73g
400 × 4.73 = 1,891.67g
Convert grams to ounces: 1,891.67 ÷ 28.3495 = 66.73 oz

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.
