How Much Is 12 Ounces of Peanut Butter in Tablespoons?
12 ounces of peanut butter equals 21.10 tbsp. Peanut butter has a density of 258g per cup. A lighter ingredient like flour (125g/cup) would fill more volume at the same weight, which is why ingredient-specific conversions matter.
Formula and Step-by-Step
- Start with 12 ounces of peanut butter
- Convert ounces to grams: 12 × 28.35 = 340.19g
- 1 cup of peanut butter = 258g
- 340.19g ÷ 258g/cup = 1.32 cups × 16 = 21.10 tablespoons
The same formula works for any amount. Multiply (or divide) by the density, then convert units as needed.
Measuring Tip
