About Converting Cubic Centimeters to Cubic Decimeters
Cubic Centimeter and Cubic Decimeter 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. Both are cubic metric volume unit units.
Formula
cubic decimeters = cubic centimeters × 0.001
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 cubic decimeter equals 0.001 base units, so dividing one by the other gives the direct cubic centimeter-to-cubic decimeter factor of 0.001.
Simple example
1 cm3 × 0.001 = 0.001 dm3
1 cubic centimeter = 0.001 cubic decimeters.
Real-world example
10 cm3 × 0.001 = 0.01 dm3
10 cubic centimeters = 0.01 cubic decimeters.

Frequently asked questions
How many cubic decimeters are in 1 cubic centimeter?
1 cubic centimeter equals 0.001 cubic decimeters, using the exact defined conversion factor rather than an estimate.
How do I convert cubic centimeter to cubic decimeter?
Multiply the cubic centimeter value by 0.001. The converter above does this instantly to whatever precision you set.
How do I convert cubic decimeter back to cubic centimeter?
Use the reverse factor: 1 cubic decimeter equals 1,000 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 cubic decimeter?
Cubic Decimeter (dm3) is a unit of volume.
Is the cubic centimeter to cubic decimeter conversion exact?
Yes. Both cubic centimeter and cubic decimeter are defined by fixed standards rather than physical artifacts, so the factor of 0.001 used above is exact to as many digits as you choose to display.
