Find out how many teaspoons are in a milliliter. Convert milliliters to teaspoons instantly and see a chart from 1 to 1,000 milliliters. Free and exact. — On the scale, 1 milliliter lines up with 0.2029 teaspoon; read any other amount straight across.

Divide the milliliters (millilitres) by 4.929 to get US teaspoons. Dividing by 5 is simpler and lands very close, because a metric teaspoon holds exactly 5 ml.

Small metric amounts come out like this:

1.25 ml is 0.2536 tsp, about a quarter teaspoon.
7.5 ml is 1.522 tsp, about one and a half teaspoons.
20 ml is 4.058 tsp, about four teaspoons.

For the smallest amounts, a 1/8 tsp spoon holds 0.6161 ml. Above 15 ml, tablespoons are faster than counting teaspoons. The milliliters to tablespoons converter handles those amounts.

US vs UK teaspoons

The teaspoon in UK, Australian, Canadian and New Zealand recipes is the metric one of 5 ml. The US teaspoon holds 4.929 ml, a gap too small to see in a spoon.

So 5 ml equals 1.014 US teaspoons, and you can use either spoon for a metric recipe. The difference only shows up when you add up dozens of spoonfuls, such as when you scale a spice blend up for a large batch.

Reading an oral syringe or dosing cup

Many liquid medicines sold over the counter come with a dosing cup, dropper or oral syringe. FDA guidance asks makers to mark these devices in the same units as the directions on the package and to write milliliters as mL (FDA guidance).

If the directions give mL, measure with the device that came in the box rather than converting to kitchen spoons. The same guidance describes household spoons as a less accurate way to measure medicine.

Milliliters and teaspoons: questions

Is 5 ml a teaspoon?

It is exactly one metric teaspoon, the size used in UK and Australian recipes. Against the slightly smaller US teaspoon, 5 ml comes to 1.014 spoons, a difference no cook will notice.

How many teaspoons is 10 ml?

10 ml is 2.029 tsp, so two level teaspoons match it closely. It is also 0.6763 tbsp, about two thirds of a tablespoon, which is why two teaspoons are the easier way to measure it.

How many teaspoons is 2.5 ml?

2.5 ml is 0.5072 tsp, which is half a teaspoon for any practical purpose. A metric half-teaspoon holds exactly 2.5 ml, and the US half-teaspoon holds 2.464 ml.

How many teaspoons are in 15 ml?

15 ml equals 3.043 tsp. That is one metric tablespoon, and in both systems three teaspoons make a tablespoon. A US tablespoon holds a little less than 15 ml, so three level US teaspoons are close enough.
