How to Convert Cups to Cubic Feet

To convert a measurement in cups to a measurement in cubic feet, multiply the volume by the following conversion ratio: 0.008355 cubic feet/cup.

Since one cup is equal to 0.008355 cubic feet, you can use this simple formula to convert:

cubic feet = cups × 0.008355

The volume in cubic feet is equal to the volume in cups multiplied by 0.008355.

For example, here's how to convert 500 cups to cubic feet using the formula above.

cubic feet = (500 c × 0.008355) = 4.177517 ft³

Cups and cubic feet 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.
