Milliliters
A Milliliter is a metric volume unit equal to one-thousandth of a liter. It is generally used to measure very small amounts of liquid in cooking or medication. For example, a standard teaspoon is about 5 ml.
A milliliter is exactly one cubic centimeter, and a milliliter of water weighs about a gram – so 250mL of water is 250g.
