You can't directly convert milliliters (ml) to spoon size because spoons come in different sizes.

Here's a breakdown:

* Teaspoon: A standard teaspoon holds approximately 5 ml.

* Tablespoon: A standard tablespoon holds approximately 15 ml.

Therefore, 1 ml is about 1/5 of a teaspoon.

Important Note: When measuring medicine, it's best to use a measuring spoon specifically designed for medication, as they are more accurate than standard kitchen spoons.
