How Much Is 13.65 Ounces of Peanut Butter in Tablespoons?
13.65 ounces of peanut butter equals 24.00 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 13.65 ounces of peanut butter
- Convert ounces to grams: 13.65 × 28.35 = 386.97g
- 1 cup of peanut butter = 258g
- 386.97g ÷ 258g/cup = 1.50 cups × 16 = 24.00 tablespoons
The same formula works for any amount. Multiply (or divide) by the density, then convert units as needed.
Measuring Tip
Spoon peanut butter into the measuring spoon and pack gently to fill gaps. Do not scoop directly from the jar, which traps air.

Understanding the Units
What is an Ounce?
Weight ounces and fluid ounces are different measurements. A fluid ounce measures volume (29.574 ml), while an ounce measures weight (28.35g). They only align for water, where 1 fl oz weighs approximately 1 oz.
What is a Tablespoon?
Tablespoon sizes differ by country. A US tablespoon is 14.787 ml, close to the 15 ml metric standard used in most countries. An Australian tablespoon is 20 ml, about 35% larger than US. An imperial tablespoon is 17.758 ml. If your recipe comes from Australia, the larger tablespoon size can make a real difference.
