How to Convert Cups to Cubic Inches

Calculators can be used to convert measurements from one unit to another

To convert a cup measurement to a cubic inch measurement, multiply the volume by the conversion ratio. One cup is equal to 14.4375 cubic inches, so use this simple formula to convert:

cubic inches = cups × 14.4375

The volume in cubic inches is equal to the cups multiplied by 14.4375.

For example, here's how to convert 5 cups to cubic inches using the formula above.
5 c = (5 × 14.4375) = 72.1875 in³

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


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 cup is equal to just under 236.6 milliliters, but in nutrition labelling, one cup is equal to 240 milliliters.

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.

Cubic Inches

The cubic inch is a unit of volume that is equal to the space consumed by a cube with sides that are one inch in all directions.

The cubic inch is a US customary and imperial unit of volume. A cubic inch is sometimes also referred to as a cubic in. Cubic inches can be abbreviated as in³, and are also sometimes abbreviated as cu inch, cu in, or CI. For example, 1 cubic inch can be written as 1 in³, 1 cu inch, 1 cu in, or 1 CI.

Understanding the Metric System

The metric system makes it relatively easy to convert from one metric unit to another metric unit. The metric system uses a base unit, think meters or grams, and a prefix such as kilo or milli. The prefixes differ from the base units by differing powers of 10. So to convert within the metric system it’s usually a matter of multiplying or dividing by one of the powers of 10.

Here is a list of some of the common metric prefixes:

  • “kilo” – 1,000x larger
  • “hecto” – 100x larger
  • “deca” – 10x larger
  • “deci” – 10x smaller
  • “centi” – 100x smaller
  • “milli” – 1,000x smaller

There is a helpful mnemonic for remembering the prefixes: “King Henry Died Until Drinking Chocolate Milk.”
The u in Until refers to the base unit.
