About This Conversion
Teaspoons to milliliters is the smallest kitchen conversion and the one where using the wrong spoon does the most damage. A US teaspoon is 4.93 ml, near enough to 5 ml that the two are used interchangeably in cooking.
Medicine is the exception where the 5 ml figure is the real unit. Dosing spoons and oral syringes are calibrated to exactly 5 ml, and an ordinary cutlery teaspoon can hold anywhere from 3 to 7 ml, which is why medicine instructions specify a measured spoon rather than any spoon.
