Cubic Centimeters to Cups formula
The factor from cubic centimeters to cups is 0.00422675284.
cup = cm³ × 0.00422675284
Why this factor: the cubic centimeter and the cup are both defined against the liter, so dividing one definition by the other gives 0.00422675284 directly. Both definitions are set out in full below.
To go the other way, divide by 0.00422675284 — or use the Cups to Cubic Centimeters converter, which is the same calculation reversed.
Worked example
Take 2 cm³ and multiply by the factor 0.00422675284: the result is 0.008454 cup.
2 cm³ × 0.00422675284 = 0.008454 cup
The converter above does this for any value you type, in either direction.
What is a cubic centimeter?
A cubic centimeter is the volume of a one-centimeter cube, identical to a milliliter.
Definition: Exactly 1×10⁻⁶ cubic meter, which is exactly 1 mL.
Where it is used: Engine displacement on motorcycles and small engines, and medical volumes where it is written 'cc'.
What is a cup?
A US customary cup is the standard cooking volume measure in American recipes.
Definition: Exactly one sixteenth of a US liquid gallon, so exactly 236.5882365 milliliters.
Where it is used: American recipes and baking, where dry and liquid ingredients alike are measured by cup.
Worth knowing: Nutrition labels use the US *legal* cup of exactly 240 mL, and a metric cup is 250 mL — three slightly different cups are in circulation.
Cubic Centimeters vs Cups
The cubic centimeter is a metric unit while the cup is a US customary unit. That is why the factor between them is not a round number: the two systems were defined independently and only later tied together by exact agreement.
