Formula and Step-by-Step

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

Start with 21.15 teaspoons of butter
1 teaspoon of butter = 4.73g
21.15 × 4.73 = 100.02g
Convert grams to ounces: 100.02 ÷ 28.3495 = 3.53 oz

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.
