Formula and Step-by-Step

teaspoons × 5.38g/tsp ÷ 28.3495g/oz = ounces
  1. Start with 8 teaspoons of peanut butter
  2. 1 teaspoon of peanut butter = 5.38g
  3. 8 × 5.38 = 43g
  4. Convert grams to ounces: 43 ÷ 28.3495 = 1.52 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?

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.

Frequently Asked Questions

About 1.52 oz, based on peanut butter having a density of 258g per cup. The exact amount depends on how the ingredient is measured and the specific product.
Multiply the number of teaspoons by 5.38 (grams per teaspoon for peanut butter), then divide by 28.3495 to convert grams to ounces. For 8 teaspoons: 8 × 5.38 = 43g, then 43 ÷ 28.3495 = 1.52 oz.
For the most accurate results, weigh peanut butter on a kitchen scale. If measuring by volume, spoon the ingredient into the measuring spoon and level it off with a straight edge rather than scooping directly.
Weight-per-cup values vary because of differences in how the ingredient is measured (spooned vs scooped), grind size, moisture content, and settling during storage. Our values use standardized measurement methods from established culinary references.
