About Converting Carats per Cubic Centimeter to Kilograms per Cubic Millimeter
Carat per Cubic Centimeter and Kilogram per Cubic Millimeter both measure density — mass per unit volume — a property used to identify materials, check manufacturing quality, and predict whether something floats or sinks. As a fixed reference point, water has a density of exactly 1000 kg/m³ (1 g/cm³, 1 g/mL) at its temperature of maximum density, which is why many density figures in science and engineering are quoted relative to water. Both are mass per volume density units.
Formula
kilograms per cubic millimeter = carats per cubic centimeter × 2e-7
This factor comes from each unit's defined relationship to the category's base unit: 1 carat per cubic centimeter equals 200 base units, and 1 kilogram per cubic millimeter equals 1000000000 base units, so dividing one by the other gives the direct carat per cubic centimeter-to-kilogram per cubic millimeter factor of 2e-7.
Simple example
1 ct/cm3 × 2e-7 = 2e-7 kg/mm3
1 carat per cubic centimeter = 2e-7 kilograms per cubic millimeter.
Real-world example
1,000 ct/cm3 × 2e-7 = 0.0002 kg/mm3
1,000 carats per cubic centimeter = 0.0002 kilograms per cubic millimeter.

Frequently asked questions
How many kilograms per cubic millimeter are in 1 carat per cubic centimeter?
1 carat per cubic centimeter equals 2e-7 kilograms per cubic millimeter, using the exact defined conversion factor rather than an estimate.
How do I convert carat per cubic centimeter to kilogram per cubic millimeter?
Multiply the carat per cubic centimeter value by 2e-7. The converter above does this instantly to whatever precision you set.
How do I convert kilogram per cubic millimeter back to carat per cubic centimeter?
Use the reverse factor: 1 kilogram per cubic millimeter equals 5,000,000 carats per cubic centimeter. You can also use the swap control in the converter above to flip the direction instantly.
What is a carat per cubic centimeter?
Carat per Cubic Centimeter (ct/cm3) is a unit of density.
What is a kilogram per cubic millimeter?
Kilogram per Cubic Millimeter (kg/mm3) is a unit of density.
Is the carat per cubic centimeter to kilogram per cubic millimeter conversion exact?
Yes. Both carat per cubic centimeter and kilogram per cubic millimeter are defined by fixed standards rather than physical artifacts, so the factor of 2e-7 used above is exact to as many digits as you choose to display.
What's the difference between density and mass concentration?
Density is the mass of a pure substance or material per unit volume. Mass concentration is the mass of one component — like a dissolved solute — within a mixture's total volume. The two use the same kind of units but describe different physical situations.
