1 cubic centimeter = 0.004226752838 US cups

How to convert cubic centimeters to US cups

To convert cubic centimeters to US cups, multiply the number of cubic centimeters by 0.004226752838. The factor is rounded to 10 significant digits. To go the other way, multiply US cups by 236.5882365.

US cups = cubic centimeters × 0.004226752838

Example: 10 cubic centimeters = 0.04226752838 US cups.

Pints, quarts, gallons and fluid ounces differ between the US and the UK. Units are labeled 'US' or 'imperial' to avoid confusion.

About these units

Cubic Centimeter (cm³)

Metric (SI)Current unit

Exactly one milliliter. Used for engine displacement (as 'cc') and in medicine.

Cubic centimeter is the volume of a cube one centimeter on each side, and it belonged to the old centimeter-gram-second system of units, in which one cubic centimeter of water was meant to weigh about one gram. Its famous abbreviation, cc, is not an SI symbol at all. The official symbol is cm³, yet cc stuck in medicine, cooking and engineering because it is quick to write and say.

A cubic centimeter equals exactly one milliliter, so the two names are interchangeable and which one you meet depends on the field. Doses are often written in cc. Motorcyclists, scooter makers and engine builders use it for displacement: the swept volume is the bore area times the stroke times the number of cylinders, so a 1,000 cc sport bike can move eight times as much air per cycle as a 125 cc scooter. One cubic inch is 16.38706 cubic centimeters, which lets Americans and Europeans compare engines.

1 cubic centimeter = 0.001 liters (exactly).

US Cup (cup)

US customaryCurrent unit

One sixteenth of a US gallon, 236.588 mL (8 US fluid ounces). The standard US recipe cup.

Cups began as household drinking vessels, not scientific units, which is why they remain the messiest measures in the kitchen. The US customary cup was defined by slicing up the gallon: half a pint, or eight US fluid ounces, about 236.6 milliliters. Unlike the larger units, nobody ever fixed it to a physical vessel, so it exists only as a fraction of the gallon.

The customary cup is not the only American cup. For nutrition labels, US regulation defines a cup as exactly 240 milliliters, a rounder figure that sits slightly above the customary size. Packaged foods therefore list a serving in the legal cup while a measuring cup from the hardware store follows the customary definition. The gap is 3.4 milliliters, which hardly matters for soup but can matter in baking. Cup measures also hide the weight of dry ingredients, since a cup of sifted flour and a cup of packed flour differ substantially, which is why much of the world prefers grams.

1 US cup = 0.2365882365 liters (exactly).
