What is a milliliter?
A milliliter is one thousandth of a liter, and is exactly the same volume as a cubic centimeter.
Definition: Exactly 0.001 liter, which is exactly 1 cm³.
Where it is used: Medicine doses, cosmetics, recipe quantities, and laboratory work.
Worth knowing: 1 mL = 1 cm³ = 1 cc exactly, so these three units are interchangeable.
What is a quart?
A quart is a quarter of a US gallon — two pints.
Definition: Exactly one quarter of a US liquid gallon, so exactly 0.946352946 liter.
Where it is used: Milk, motor oil, stock and broth, and ice cream in the US.
Worth knowing: Close to a liter but about 5% smaller, which makes it an easy source of recipe error.
Milliliters vs Quarts
The milliliter is a metric unit while the quart is a US customary unit. That is why the factor between them is not a round number: the two systems were defined independently and only later tied together by exact agreement.
