How to Convert Fluid Ounces to Teaspoons

To convert a measurement in fluid ounces to a measurement in teaspoons, multiply the volume by the following conversion ratio: 6 teaspoons/fluid ounce.

Since one fluid ounce is equal to 6 teaspoons, you can use this simple formula to convert:

teaspoons = fluid ounces × 6

The volume in teaspoons is equal to the volume in fluid ounces multiplied by 6.

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

teaspoons = (5 fl oz × 6) = 30 tsp

How Many Teaspoons Are in a Fluid Ounce?

There are 6 teaspoons in a fluid ounce, which is why we use this value in the formula above.

1 fl oz = 6 tsp

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

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.[1]

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 Teaspoon?
