How to Convert Teaspoons to Ounces

Scales are used to measure weight

To convert a teaspoon measurement to an ounce measurement, divide the volume multiplied by the density of the ingredient or material by 5.751669.

You can use this simple formula to convert:

ounces = teaspoons × ingredient density5.751669

Thus, the volume in ounces is equal to the teaspoons times the density of the ingredient or material divided by 5.751669.

For example, here's how to convert 5 teaspoons to ounces for an ingredient with a density of 0.7 g/mL.
5 tsp = 5 × 0.75.751669 = 0.608519074659 oz

This calculator converts to ounces in weight, if you're trying to convert to a volume measurement in fluid ounces try our teaspoons to fluid ounces calculator.

Teaspoons 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.

Teaspoons

The teaspoon is a unit of volume equal to one-third of a tablespoon.[2] One teaspoon is equal to around 4.9 milliliters, but in nutrition labeling, one teaspoon is equal to exactly 5 milliliters.[3]

The teaspoon is a US customary unit of volume. Teaspoons can be abbreviated as tsp, and are also sometimes abbreviated as t, ts, or tspn. For example, 1 teaspoon can be written as 1 tsp, 1 t, 1 ts, or 1 tspn.

Ounces

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.
