There are 4.93 mL (milliliters) in a teaspoon and 0.203 teaspoons in one mL. These conversions refer to the US teaspoon. However, teaspoon sizes can vary in different parts of the world. Read on to learn all the details about teaspoons and milliliters, and how to convert milliliters to teaspoons and teaspoons to milliliters.
How many milliliters are in a teaspoon?
One teaspoon is equal to 4.93 milliliters, meaning there are 4.93 mL per teaspoon. This measurement applies to the US teaspoon.
Variations:
Other places around the world use different sizes for a teaspoon:

- 1 Metric teaspoon = 5 mL
There is a very small difference between a US teaspoon and a metric teaspoon and, in many situations, they can be used interchangeably. However, if you require very precise measurements, make sure to use the right teaspoon.
- How many milliliters (mL) are in two teaspoons? There are 9.86 mL in two teaspoons.
- How many milliliters (mL) are in a half teaspoon? There are 2.46 mL in a half teaspoon.
- How many milliliters (mL) are in a quarter (¼ or 0.25) teaspoon? There are 1.23 mL in 0.25 teaspoons.
Convert teaspoons to milliliters (tsp to mL)
To convert teaspoons to milliliters, multiply the number of teaspoons by 4.93. For example, 5 tsp is 5 x 4.93 = 24.65 mL.
Variations:
- For a metric teaspoon, multiply the number of teaspoons by 5. For example, 3 metric teaspoons in milliliters would be 3 x 5 = 15 mL.
- For an imperial teaspoon, multiply the number of teaspoons by 5.92. For example, 3 imperial teaspoons in milliliters would be 3 x 5.92 = 17.76 mL.
