How to convert milliliters to teaspoons
1 milliliter = 0.2028841362 teaspoons. To convert milliliters to teaspoons, divide by 4.928921594 (or multiply by 0.2028841362). A milliliter is one thousandth of a liter, the same as one cubic centimeter. A US teaspoon is one sixth of a fluid ounce, about 4.93 ml.
Worked examples
- 2.5 milliliters = 0.50721 tsp (2.5 ÷ 4.9289216)
- 5 milliliters = 1.01442 tsp (5 ÷ 4.9289216)
- 15 milliliters = 3.04326 tsp (15 ÷ 4.9289216)
Where this conversion comes up
Milliliters are used for medicine doses, drinks, perfume and recipes outside the US; teaspoons for baking, spices and liquid medicine. A US teaspoon is 4.93 ml, so 5 ml (the standard medicine teaspoon) is 1.01 tsp and 15 ml is 3 tsp (one tablespoon). Children's medicine should be measured with a syringe, not a kitchen spoon.
Quick estimate
Divide by 5 (1.4% low).
Common mistakes
- Multiplying instead of dividing. A teaspoon is larger than a milliliter, so the number of teaspoons must come out smaller: 2.5 milliliters = 0.50721 tsp.
- Rounding too early. Keep the full factor until the last step; rounding 0.203 to 0.2 first puts large values noticeably off.
