How Much Is 1 Teaspoon of Peanut Butter in Ounces?
1 teaspoon of peanut butter equals 0.19 oz. Peanut butter has a density of 258g per cup (5.38g per teaspoon), which means it's relatively light compared to other common cooking ingredients. For comparison, 1 teaspoon of honey would be 0.25 oz.
Formula and Step-by-Step
- Start with 1 teaspoon of peanut butter
- 1 teaspoon of peanut butter = 5.38g
- 1 × 5.38 = 5.38g
- Convert grams to ounces: 5.38 ÷ 28.3495 = 0.19 oz
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.

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?
An ounce (oz) is a US customary unit of weight equal to 28.3495 grams or 1/16 of a pound. In cooking, "ounces" refers to weight (avoirdupois ounces), not fluid ounces which measure volume.
