Small metric quantities appear in imported recipes, liquid supplements and children’s medicine. Teaspoons are what an American kitchen has on hand to measure them.
10 milliliters of vanilla extract is 2.02884 teaspoons, so two teaspoons is near enough for a cake.
What People Get Wrong
A 5 mL dose is 1.01442 teaspoons, so rounding to one teaspoon is slightly short. For medicine use the supplied syringe rather than converting.

About These Units
The milliliter
A milliliter is one thousandth of a liter and is exactly the same volume as one cubic centimeter. It is the standard unit in metric recipes and on medicine labels.
The teaspoon
A US teaspoon is one third of a tablespoon, or about 4.93 milliliters. Metric recipes often round the teaspoon to a flat 5 milliliters, which is close enough for cooking but not for medicine.
Definitions follow NIST Handbook 44, Appendix C. See how we calculate for the exact values and rounding rules.
