About Milliliter and Teaspoon

The teaspoon is about 4.93 milliliters in US recipe measure, one third of a tablespoon. Baking ingredients like spices, salt, and leavening are specified in teaspoons. One Milliliter equals 0.2028841362 Teaspoons (1 ml = 0.2028841362 tsp). Milliliter is used in liquid medicine doses and in cosmetics and toiletries. Teaspoon is used in baking spices and leavening.

Precision and Rounding:US and imperial volume units share names but differ in size (an imperial gallon is about 20% larger than a US gallon), so confirm which system a figure uses before converting. Kitchen work tolerates rounding to the nearest milliliter or quarter-teaspoon; fuel, chemistry, and brewing need three or more decimal places.

Conversion factors per NIST Special Publication 811 and the BIPM SI Brochure (9th edition) (reference).
