Milliliter (ml) to Teaspoon (tsp)
To convert milliliters to teaspoons using US measurements, divide by 4.929. In the US, 1 teaspoon is 4.929 ml — slightly less than the 5 ml metric teaspoon. For most cooking purposes, dividing by 5 gives a result accurate enough. This conversion is also useful for children's liquid medicine dosages, which are commonly given in milliliters on packaging.
Frequently asked questions
10 ml ÷ 4.929 ml = approximately 2.03 US teaspoons — effectively 2 teaspoons. Using the metric approximation (÷5) gives exactly 2, which is close enough for medicine or cooking.
5 ml ÷ 4.929 ml = approximately 1.01 US teaspoons — essentially 1 teaspoon. For medicine dosages, a calibrated oral syringe is more reliable than a kitchen teaspoon.
No — kitchen teaspoons are not standardized and can vary widely in volume. The FDA recommends using a calibrated measuring device such as an oral syringe or dosing cup for liquid medications. Never use a regular spoon for medicine, especially for children's doses.
15 ml ÷ 4.929 ml ≈ 3.04 US teaspoons — essentially 3 teaspoons, which equals 1 US tablespoon. This is a frequently needed conversion in recipes and medicine instructions.
