About Converting Carats per Cubic Millimeter to Kilograms per Milliliter
Carat per Cubic Millimeter and Kilogram per Milliliter 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 milliliter = carats per cubic millimeter × 0.2
This factor comes from each unit's defined relationship to the category's base unit: 1 carat per cubic millimeter equals 200000 base units, and 1 kilogram per milliliter equals 1000000 base units, so dividing one by the other gives the direct carat per cubic millimeter-to-kilogram per milliliter factor of 0.2.
Simple example
1 ct/mm3 × 0.2 = 0.2 kg/mL
1 carat per cubic millimeter = 0.2 kilograms per milliliter.
Real-world example
1,000 ct/mm3 × 0.2 = 200 kg/mL
1,000 carats per cubic millimeter = 200 kilograms per milliliter.

Frequently asked questions
How many kilograms per milliliter are in 1 carat per cubic millimeter?
1 carat per cubic millimeter equals 0.2 kilograms per milliliter, using the exact defined conversion factor rather than an estimate.
How do I convert carat per cubic millimeter to kilogram per milliliter?
Multiply the carat per cubic millimeter value by 0.2. The converter above does this instantly to whatever precision you set.
How do I convert kilogram per milliliter back to carat per cubic millimeter?
Use the reverse factor: 1 kilogram per milliliter equals 5 carats per cubic millimeter. You can also use the swap control in the converter above to flip the direction instantly.
What is a carat per cubic millimeter?
Carat per Cubic Millimeter (ct/mm3) is a unit of density.
What is a kilogram per milliliter?
Kilogram per Milliliter (kg/mL) is a unit of density.
Is the carat per cubic millimeter to kilogram per milliliter conversion exact?
Yes. Both carat per cubic millimeter and kilogram per milliliter are defined by fixed standards rather than physical artifacts, so the factor of 0.2 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.
