How to Convert Ounces to Tablespoons

Since ounces are a unit of mass and tablespoons are a unit of volume, 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 ounces and tablespoons of an ingredient or substance, we must either multiply or divide by its density, depending on which direction we are performing the conversion.

Ounces to Tablespoons Formula

To convert a measurement in ounces to tablespoons, divide the weight by the density of the ingredient or material. Note that in order for this to work, the density must be in ounces per tablespoon (oz/tbsp).

If the density is given in grams per milliliter (g/mL), then first divide 1.9172 by the density to convert to oz/tbsp.

For a density given in g/mL, you can use this simple formula to convert:

tablespoons = ounces × 1.9172 / density

Thus, the volume in tablespoons is equal to the weight in ounces times 1.9172 divided by the density of the ingredient, substance, or material.

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

tablespoons = 5 oz × 1.9172 / 0.7 g/mL = 13.6944 tbsp

How Many Tablespoons Are in a Ounce?

The actual volume of a ounce will vary depending on the material's density. The conversion table below shows how many tablespoons of various wet and dry ingredients are in a ounce.

Ounce measurements converted to tablespoons for commonly used cooking and baking ingredients.

When to Convert Ounces to Tablespoons

Ounces and tablespoons 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 weight to volume 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 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.[3]

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 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.

Remember that liquid measurements use the fluid ounce, which is a volume measurement.

The US fluid ounce is a unit of volume equal to 1/16 of a pint or 1/8 of a cup. The fluid ounce is sometimes referred to as just an "ounce" but should not be confused with the unit of weight. One fluid ounce is equal to approximately 29.5735 milliliters, but in nutrition labeling, one fluid ounce is rounded to exactly 30 milliliters.[4]

It's also denoted a little differently, so you can distinguish both forms of measurement on packaging or in recipes.

The fluid ounce is a US customary unit of volume. Fluid ounces can be abbreviated as fl oz, and are also sometimes abbreviated as oz fl. For example, 1 fluid ounce can be written as 1 fl oz or 1 oz fl.

What Is a Tablespoon?

A tablespoon is a unit of volume equal to three teaspoons or ½ fluid ounce.[5] One tablespoon is equal to 14.7868 milliliters, but for nutrition labeling, one tablespoon is rounded to 15 milliliters.[4]

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.
