How to Convert Tablespoons to Fluid Ounces

To convert a measurement in tablespoons to a measurement in fluid ounces, divide the volume by the following conversion ratio: 2 tablespoons/fluid ounce.

Since one fluid ounce is equal to 2 tablespoons, you can use this simple formula to convert:

fluid ounces = tablespoons ÷ 2

The volume in fluid ounces is equal to the volume in tablespoons divided by 2.

For example, here's how to convert 5 tablespoons to fluid ounces using the formula above.

fluid ounces = (5 tbsp ÷ 2) = 2.5 fl oz

How Many Fluid Ounces Are in a Tablespoon?

There are 0.5 fluid ounces in a tablespoon, which is why we use this value in the formula above.

1 tbsp = 0.5 fl oz

Tablespoons and fluid ounces are both units used to measure volume. Keep reading to learn more about each unit of measure.

What Is a Tablespoon?

A tablespoon is a unit of volume equal to three teaspoons or ½ fluid ounce.[1] One tablespoon is equal to 14.7868 milliliters, but for nutrition labeling, one tablespoon is rounded to 15 milliliters.[2]

What Is a Fluid Ounce?

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.[2]

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.
