How Much Is 1.5 Teaspoons of Peanut Butter in Ounces?
1.5 teaspoons of peanut butter weighs 0.28 oz. This is based on peanut butter having a density of 258g per cup. Because teaspoons measure volume and ounces measure weight, the result depends on the ingredient, and a different ingredient would give a different result for the same 1.5 teaspoons.
Formula and Step-by-Step
- Start with 1.5 teaspoons of peanut butter
- 1 teaspoon of peanut butter = 5.38g
- 1.5 × 5.38 = 8.06g
- Convert grams to ounces: 8.06 ÷ 28.3495 = 0.28 oz
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 a Teaspoon?
In baking, teaspoon measurements are critical for ingredients where precision changes the outcome. Too much baking soda (1 tsp = 6g) creates a metallic taste, while too little means flat results.
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.
