Formula and Step-by-Step

tablespoons × 14.19g/tbsp ÷ 28.3495g/oz = ounces
  1. Start with 8 tablespoons of butter
  2. 1 tablespoon of butter = 14.19g
  3. 8 × 14.19 = 113.5g
  4. Convert grams to ounces: 113.5 ÷ 28.3495 = 4.00 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 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?

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 4.00 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 tablespoons by 14.19 (grams per tablespoon for butter), then divide by 28.3495 to convert grams to ounces. For 8 tablespoons: 8 × 14.19 = 113.5g, then 113.5 ÷ 28.3495 = 4.00 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.
Reverse the conversion: 4.00 oz × 28.3495 = 113.5g, then 113.5g ÷ 14.19 = 8 tablespoons. Or use the Ounces to Tablespoons converter.
