Formula and Step-by-Step

teaspoons × 4.73g/tsp ÷ 28.3495g/oz = ounces
  1. Start with 150 teaspoons of butter
  2. 1 teaspoon of butter = 4.73g
  3. 150 × 4.73 = 709.38g
  4. Convert grams to ounces: 709.38 ÷ 28.3495 = 25.02 oz

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

Measuring Tip

Softened butter and melted butter measure differently by volume. Melted butter settles with no air pockets, giving a slightly higher weight per cup.

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.

Frequently Asked Questions

About 25.02 oz, based on butter having a density of 227g per cup. The exact amount depends on how the ingredient is measured and the specific product.
Multiply the number of teaspoons by 4.73 (grams per teaspoon for butter), then divide by 28.3495 to convert grams to ounces. For 150 teaspoons: 150 × 4.73 = 709.38g, then 709.38 ÷ 28.3495 = 25.02 oz.
For the most accurate results, weigh 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.
Fat content has a small effect on density. Higher-fat versions are slightly lighter per volume because fat is less dense than water. The difference is usually under 5%, so this conversion works well for standard varieties.
