About Converting Cubic Centimeters to Milliliters
Cubic Centimeter and Milliliter appear side by side at fuel pumps and on beverage labels, since the US measures liquids in gallons while most of the world uses liters. Specifically: Cubic metric volume unit, and milliliter is 0.001 liter units.
Formula
milliliters = cubic centimeters × 1
This factor comes from each unit's defined relationship to the category's base unit: 1 cubic centimeter equals 0.000001 base units, and 1 milliliter equals 0.000001 base units, so dividing one by the other gives the direct cubic centimeter-to-milliliter factor of 1.
Simple example
1 cm3 × 1 = 1 mL
1 cubic centimeter = 1 milliliters.
Real-world example
10 cm3 × 1 = 10 mL
10 cubic centimeters = 10 milliliters.
Conversion table
| Cubic Centimeter (cm3) | Milliliter (mL) |

Understanding the Cubic Centimeter (cm3)
Cubic metric volume unit.
Understanding the Milliliter
Milliliter (mL) measures volume. A milliliter is one-thousandth of a liter, equal to one cubic centimeter. It is classified as a SI derived (metric prefix) unit.
Where it's used: Standard small-volume unit worldwide
Uses of the Milliliter today
- Medicine dosing (worldwide, including in the US)
- Cooking and recipe measurement outside the US
- Beverage and small-container labeling
History of the Milliliter
The milliliter follows directly from the liter via the 'milli-' SI prefix. It is notable as one of the few metric units in routine US use, since medicine dosing (syringes, liquid medication) is specified in milliliters even in the US.
Historical origin. Milliliter was not the invention of a single named person; it developed through the process described above.
Milliliter — sources
- BIPM SI Brochure — SI prefixes — Defines 'milli-' as the prefix for 10⁻³.

Frequently asked questions
How many milliliters are in 1 cubic centimeter?
1 cubic centimeter equals 1 milliliters, using the exact defined conversion factor rather than an estimate.
How do I convert cubic centimeter to milliliter?
Multiply the cubic centimeter value by 1. The converter above does this instantly to whatever precision you set.
How do I convert milliliter back to cubic centimeter?
Use the reverse factor: 1 milliliter equals 1 cubic centimeters. You can also use the swap control in the converter above to flip the direction instantly.
What is a cubic centimeter?
Cubic Centimeter (cm3) is a unit of volume.
What is a milliliter?
Milliliter (mL) measures volume. A milliliter is one-thousandth of a liter, equal to one cubic centimeter. It is classified as a SI derived (metric prefix) unit.
Is the cubic centimeter to milliliter conversion exact?
Yes. Both cubic centimeter and milliliter are defined by fixed standards rather than physical artifacts, so the factor of 1 used above is exact to as many digits as you choose to display.
