How Much Is 1 Ounce of Peanut Butter in Tablespoons?
1 ounce of peanut butter equals 1.76 tbsp. That's 28.35g, and Peanut butter has a density of 258g per cup. Because ounces measure weight and tablespoons measure volume, the result depends on the ingredient's density.
Formula and Step-by-Step
- Start with 1 ounce of peanut butter
- Convert ounces to grams: 1 × 28.35 = 28.35g
- 1 cup of peanut butter = 258g
- 28.35g ÷ 258g/cup = 0.11 cups × 16 = 1.76 tablespoons
The same formula works for any amount. Multiply (or divide) by the density, then convert units as needed.
Measuring Tip
Peanut butter should be stirred before measuring if the oil has separated. An unmixed jar will give inconsistent measurements.
