Formula and Step-by-Step

grams ÷ 258g/cup × 48 = teaspoons
  1. Start with 21.5 grams of peanut butter
  2. 1 cup of peanut butter = 258g
  3. 21.5g ÷ 258g/cup = 0.08 cups × 48 = 4.00 teaspoons

The same formula works for any amount. Multiply (or divide) by the density, then convert units as needed.

Measuring Tip

Peanut butter weighs 258g per cup. Natural and processed versions may have slightly different densities.

Understanding the Units

What is a Gram?

A gram (g) is a metric unit of mass equal to 1/1000 of a kilogram. It is the standard weight measurement for precise baking worldwide. Professional bakers prefer grams because they are more accurate than volume measurements.

What is a Teaspoon?

A teaspoon (tsp) is a US customary unit of volume equal to 4.929 milliliters or 1/3 of a tablespoon. It is the standard measure for spices, leaveners, extracts, and other small-quantity ingredients.

Frequently Asked Questions

About 4.00 tsp, 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.
Divide the grams by 258 (grams per cup) to get cups, then multiply by 48 to get teaspoons. For 21.5 grams: 21.5 ÷ 258 = 0.08 cups × 48 = 4.00 tsp.
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: 4.00 tsp ÷ 48 = 0.0833333 cups, then 0.0833333 × 258g/cup = 21.5g. Or use the Teaspoons to Grams converter.
