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 cup?
A US customary cup is the standard cooking volume measure in American recipes.
Definition: Exactly one sixteenth of a US liquid gallon, so exactly 236.5882365 milliliters.
Where it is used: American recipes and baking, where dry and liquid ingredients alike are measured by cup.
Worth knowing: Nutrition labels use the US *legal* cup of exactly 240 mL, and a metric cup is 250 mL — three slightly different cups are in circulation.
Milliliters vs Cups
The milliliter is a metric unit while the cup 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.
