How do you convert teaspoons to fluid ounces?

To convert teaspoons (tsp) to fluid ounces (fl oz), multiply the volume in teaspoons by 0.16667 (fluid ounces = teaspoons × 0.16667).

What is 5 teaspoons in fluid ounces?

5 teaspoons (5 tsp) is equal to 0.83333 fluid ounces (0.83333 fl oz).

Which is larger, 1 teaspoon (us) (tsp) or 1 fluid ounce (us) (fl oz)?

One fluid ounce (us) (fl oz) is larger than one teaspoon (us) (tsp). Specifically, 1 fl oz equals 6 tsp, while 1 tsp is 0.16667 fl oz.

How do I convert back from fluid ounces (us) (fl oz) to teaspoons (us) (tsp)?

To reverse the calculation from fl oz to tsp, multiply your fluid ounce (us) value by the inverse factor 6 (or divide by 0.16667). You can also click the Swap button in the tool above to flip directions in one click.

How many decimal places should I round tsp to fl oz results to?

For everyday comparisons and quick estimates, rounding to 2 decimal places is usually sufficient (for example, 5 tsp ≈ 0.83 fl oz). For engineering, laboratory, or machining specifications, select 4 or 6 decimals—or Scientific (10ⁿ) mode—in the calculator toolbar above.

How to Convert Teaspoons to Fluid Ounces

To convert teaspoons to fluid ounces, multiply the volume by the following conversion ratio: 0.1666667 fluid ounces/teaspoon.

Since one teaspoon is equal to 0.1666667 fluid ounces, you can use this simple formula to convert:

fluid ounces = teaspoons × 0.1666667

The volume in fluid ounces is equal to the volume in teaspoons multiplied by 0.1666667.

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

fluid ounces = (5 tsp × 0.1666667) = 0.8333333 fl oz

How Many Fluid Ounces Are in a Teaspoon?

There are 0.1666667 fluid ounces in a teaspoon, which is why we use this value in the formula above.

1 tsp = 0.1666667 fl oz|1 fl oz = 6 tsp

Our teaspoon to fluid ounce calculator automatically converts your volume measurements with full decimal and scientific precision across US customary, imperial, and SI metric standards.

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

What Is a Teaspoon?

A teaspoon is a unit of volume equal to 0.0049289 liters (L), the base unit for volume. 1/3 of a US tablespoon (4.9289 mL). [1]

The teaspoon is classified as a US customary unit of volume. Teaspoons can be abbreviated as tsp; for example, 1 teaspoon can be written as 1 tsp.

When working with teaspoons (tsp) in formulas or technical specifications, always verify whether your target system uses SI metric, US customary, or British imperial standards.

In practice, teaspoons (tsp) are widely used across fine-tolerance laboratory, analytical, and micro-scale volume measurements within US customary workflows, engineering documentation, and technical data sheets.

What Is a Fluid Ounce?

A fluid ounce is a unit of volume equal to 0.0295735 liters (L), the base unit for volume. 1/128 of a US gallon (29.5735 mL). [2]

The fluid ounce is classified as a US customary unit of volume. Fluid Ounces can be abbreviated as fl oz; for example, 1 fluid ounce can be written as 1 fl oz.

When working with fluid ounces (fl oz) in formulas or technical specifications, always verify whether your target system uses SI metric, US customary, or British imperial standards.

In practice, fluid ounces (fl oz) are widely used across standard volume applications within US customary workflows, engineering documentation, and technical data sheets.

Learn more about fluid ounces in our Volume & Liquid Converter.

When converting volume between teaspoons (tsp) and fluid ounces (fl oz), keep full floating-point precision (1 tsp = 0.1666667 fl oz; 1 fl oz = 6 tsp) during intermediate calculations and round only the final fluid ounce figure to match your instrument tolerance.
