Formula and Step-by-Step

tablespoons × 16.13g/tbsp ÷ 28.3495g/oz = ounces
  1. Start with 17.58 tablespoons of peanut butter
  2. 1 tablespoon of peanut butter = 16.13g
  3. 17.58 × 16.13 = 283.48g
  4. Convert grams to ounces: 283.48 ÷ 28.3495 = 10.00 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 Tablespoon?

A tablespoon is roughly the volume of a large soup spoon. In precise terms, 1 US tablespoon equals 14.787 ml, which is very close to the 15 ml metric standard used in most of the world. Three teaspoons make one tablespoon.

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.

Frequently Asked Questions

About 10.00 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 tablespoons by 16.13 (grams per tablespoon for peanut butter), then divide by 28.3495 to convert grams to ounces. For 17.58 tablespoons: 17.58 × 16.13 = 283.48g, then 283.48 ÷ 28.3495 = 10.00 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.
Reverse the conversion: 10.00 oz × 28.3495 = 283.48g, then 283.48g ÷ 16.13 = 17.58 tablespoons. Or use the Ounces to Tablespoons converter.
