What is a milliliter?
The milliliter is one thousandth of a liter, exactly the volume of a cubic centimeter. It is the unit of medicine doses, perfume and cosmetics, and of drink labels in most countries; US bottles show it next to fluid ounces, as in 16.9 fl oz (500 ml).
What is a teaspoon?
The US teaspoon is one third of a tablespoon, about 4.93 ml, and is usually rounded to 5 ml. It measures salt, baking powder, spices and extracts. For medicine, use the syringe or cup supplied with the product rather than a kitchen spoon.
