How to Convert Tablespoons to Ounces

To convert a tablespoon measurement to an ounce measurement, divide the volume multiplied by the density of the ingredient or material by 1.917223.

You can use this simple formula to convert:

ounces = tablespoons × ingredient density / 1.917223

Thus, the volume in ounces is equal to the tablespoons times the density of the ingredient or material divided by 1.917223.

For example, here's how to convert 5 tablespoons to ounces for an ingredient with a density of 0.7 g/mL.
5 tbsp = 5 × 0.7 / 1.917223 = 1.825557 oz

Tablespoons and ounces are both commonly used to measure cooking ingredients.

For cooking applications, most chefs suggest measuring dry ingredients by weight rather than volume to improve accuracy in the measurements.[1] The density of dry ingredients can vary for a variety of reasons, such as compaction.

The best way to ensure an accurate conversion is to use a scale. When a scale is not available, a calculator like the one above is a good way to estimate the volume to weight conversion.

For cooking and baking ingredients, you can get more specific results using our butter, flour, sugar conversion calculators.

The tablespoon is a unit of volume equal to three teaspoons or ½ fluid ounce.[2] One tablespoon is equal to just under 14.8 milliliters, but in nutrition labeling, one tablespoon is equal to 15 milliliters.[3]

The tablespoon is a US customary unit of volume. Tablespoons can be abbreviated as tbsp, and are also sometimes abbreviated as T, Tbls, or Tb. For example, 1 tablespoon can be written as 1 tbsp, 1 T, 1 Tbls, or 1 Tb.


One ounce is a unit of mass/weight equal to 1/16 of a pound. The common ounce should not be confused with the troy ounce, which is equal to 1/12 of a troy pound.[4]

The ounce is a US customary and imperial unit of weight. Ounces can be abbreviated as oz; for example, 1 ounce can be written as 1 oz.
