Milliliters and teaspoons in cooking recipes
The teaspoon is the smallest spoon in a recipe, used for spices, vanilla, baking powder and salt. Its size is not the same everywhere. The US teaspoon holds about 4.93 ml, the imperial teaspoon about 5.92 ml, and the metric teaspoon on many modern measuring sets is a round 5 ml.
Because a teaspoon is so small, the differences look tiny but they add up: a recipe that asks for eight teaspoons of liquid holds about 39.4 ml with US spoons and 47.4 ml with imperial ones.
How to convert ml to teaspoons
- Enter the quantity in the Convert box and choose MilliLiters or Liters.
- In the To menu, pick US Teaspoons or Imp. Teaspoons.
- Read the converted amount in the second box. It updates as you type.
US teaspoons = milliliters ÷ 4.9289
imperial teaspoons = milliliters ÷ 5.9194Liters are multiplied by 1,000 first. Answers are rounded to three decimals.
Worked examples
10 ml of water. 10 ÷ 4.9289 = 2.0288, so you need 2.029 US teaspoons, or 1.689 imperial teaspoons.
40 ml of milk. 40 ÷ 4.9289 = 8.1154, which is 8.115 US teaspoons (about 2.7 tablespoons) and 6.757 imperial teaspoons.
5 ml, a metric teaspoon. 5 ÷ 4.9289 = 1.014, so a 5 ml spoonful is about 1.4% more than a US teaspoon. In imperial teaspoons it is 0.845.

Practical notes
- Level the spoon with a knife for dry ingredients. A rounded spoonful can hold up to 50% more.
- Three teaspoons make one tablespoon, so 15 ml is about 3 teaspoons and 45 ml is about 9.
- For amounts over a few spoonfuls, the milliliters to tablespoons converter is easier to follow.
Kitchen spoons are not accurate enough for medicine. Use the dosing syringe or cup supplied with the product and follow your pharmacist's or doctor's instructions. See our disclaimer.
