Since teaspoons are a unit of volume and ounces are a unit of mass, which are different physical quantities, we need to know one more physical quantity of the ingredient or substance to convert between them.In this case, we need to account for the density of the substance whenever we do a conversion.
Therefore, to convert between teaspoons and ounces of an ingredient or substance, we must either multiply or divide by its density, depending on which direction we are performing the conversion.
Teaspoons to Ounces Formula
To convert a measurement in teaspoons to ounces, multiply the volume by the density of the ingredient, substance, or material.Note that in order for this to work, the density must be in ounces per teaspoon (oz/tsp).
If the density is given in grams per milliliter (g/mL), then first divide the density by 5.7517 to convert to oz/tsp.
For a density given in g/mL, you can use this simple formula to convert:
ounces = teaspoons × density / 5.7517
Thus, the weight in ounces is equal to the volume in teaspoons times the density (in g/mL) of the ingredient or material divided by 5.7517.
For example, here's how to convert 5 teaspoons to ounces for an ingredient with a density of 0.7 g/mL.
ounces = 5 tsp × 0.7 g/mL / 5.7517 = 0.6085 oz
This formula is for converting to ounces in weight, if you're trying to convert to a volume measurement in fluid ounces, try our teaspoons to fluid ounces calculator.
When to Convert Teaspoons to Ounces
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 and clumping.
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, and sugar conversion calculators.
Another useful application of weight and volume conversions is chemistry.When performing chemical reactions by combining separate chemicals to produce a new chemical, one must know the exact amount of each chemical to add in order to maximize the yield of the reaction.
It is common to mix powdered chemicals with liquid, or aqueous, chemicals, and this is where it becomes very useful to convert between weights and volumes.[2]

What Is a Teaspoon?
The teaspoon is a unit of volume equal to 1/3 of a tablespoon or 1/6 of a fluid ounce.[3] One teaspoon is equal to approximately 4.929 milliliters, but in nutrition labeling, one teaspoon is equal to exactly 5 milliliters.[4]
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.

What Is an Ounce?
One ounce is a unit of mass/weight equal to 1/16 of a pound or 28.349523 grams.The common ounce should not be confused with the troy ounce, which is equal to 1/12 of a troy pound.[5]
The ounce is a US customary and imperial unit of mass. Ounces can be abbreviated as oz; for example, 1 ounce can be written as 1 oz.
An ounce is also frequently referred to as a unit of weight.While technically, an ounce is a measure of mass, and weight is actually a measure of force, the two are equivalent as long as we are performing our calculations on Earth.
For example, an object with a mass of 1 ounce weighs 1 ounce on Earth, but only weighs one-sixth of that on the moon, yet still has the same mass.
