How much is 10 mL in teaspoons or tablespoons?

10mL equals two teaspoons (2tsp).

A tablespoon is three times bigger than a teaspoon and three teaspoons equal one tablespoon (1Tbsp or 1Tb). One tablespoon also equals 15mL.

However, using a kitchen spoon to measure the dose of a medicine is NOT a good idea unless it has been properly calibrated and has been sold as a kitchen measure. Teaspoons and tablespoons are NOT official measurements and most of the silverware and cutlery that you buy to eat with has not been standardized to the same volume, and actual teaspoon volumes may range from 2.5mL to 7mL.

Measuring a dose with the cutlery you eat with will likely result in either an underdose or an overdose of the medicine.

Most liquid medicines are supplied with a free dosing cup, syringe, or measuring spoon. If not, these can be bought from a pharmacy and most supermarkets. Always use a properly calibrated measuring device to measure liquid medicines.
