How to Convert Cups to Liters

To convert a measurement in cups to a measurement in liters, multiply the volume by the following conversion ratio: 0.236588 liters/cup.

Since one cup is equal to 0.236588 liters, you can use this simple formula to convert:

liters = cups × 0.236588

The volume in liters is equal to the volume in cups multiplied by 0.236588.

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

liters = (5 c × 0.236588) = 1.182941 L

Cups and liters 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 Liter?

A liter is a unit of volume equal to 1,000 cubic centimeters or 0.264172 US gallons.[2] The liter is a special name defined for the cubic decimeter and is exactly equal to the volume of one cubic decimeter (1 decimeter is 1/10 of a meter, or 10 centimeters).

The liter is an SI accepted unit for volume for use with the metric system. A liter is sometimes also referred to as a litre. Liters can be abbreviated as L, and are also sometimes abbreviated as l or ℓ. For example, 1 liter can be written as 1 L, 1 l, or 1 ℓ.
