How to Convert Cups to Milliliters

To convert a measurement in cups to a measurement in milliliters, multiply the volume by the following conversion ratio: 236.588236 milliliters/cup.

Since one cup is equal to 236.588236 milliliters, you can use this simple formula to convert:

milliliters = cups × 236.588236

The volume in milliliters is equal to the volume in cups multiplied by 236.588236.

For example, here's how to convert 5 cups to milliliters using the formula above.

milliliters = (5 c × 236.588236) = 1,182.941182 mL

How Many Milliliters Are in a Cup?

There are 236.588236 milliliters in a cup, which is why we use this value in the formula above.

1 c = 236.588236 mL

Cups and milliliters are both units used to measure volume. Keep reading to learn more about each unit of measure.

What Is a Cup?

The cup is a unit of volume equal to 16 tablespoons or 8 fluid ounces. The cup should not be confused with the metric cup or the teacup, which are different units of volume.

One standard cup is equal to 236.588 milliliters, but for nutrition labeling, one cup is defined as 240 milliliters.[1] To further confuse things, a metric cup is equal to 250 mL, while in Japan, a cup is equivalent to only 200 mL.

The cup is a US customary unit of volume. Cups can be abbreviated as c, and are also sometimes abbreviated as C. For example, 1 cup can be written as 1 c or 1 C.

What Is a Milliliter?

The milliliter is a unit of volume equal to 1 cubic centimeter, 1/1,000 of a liter, or about 0.061 cubic inches.[2]

The milliliter is an SI unit of volume in the metric system. In the metric system, "milli" is the prefix for thousandths, or 10-3. A milliliter is sometimes also referred to as a millilitre. Milliliters can be abbreviated as mL, and are also sometimes abbreviated as ml or mℓ. For example, 1 milliliter can be written as 1 mL, 1 ml, or 1 mℓ.

Since one milliliter is equivalent to one cubic centimeter, milliliters are sometimes expressed using the abbreviation for a cubic centimeter (cc) for things such as medical dosages or engine displacements.
