A milliliters (ml) is a unit of volume in the International System of Units (SI). In SI, units of measurement are comprised of a base unit and a prefix that describes the magnitude of the unit. The base unit of the milliliters is the liter, and the prefix "milli-" indicates the magnitude 10^{-3}. In other words, a milliliter is liters.

A cup (c) is a unit of volume in the United States (US) customary system as well as in a few other systems of measurements. However, the sizes of the cups are different in these measurement systems. The US customary system is still widely used in few counties today. Unlike SI, the relationship between units of measurement within the US customary system is not as clear; it is necessary to know the specific conversions between the units of measurement even within the same system. For example, there are 8 fluid ounces in a cup, and 4 cups in a quart.
