About Converting Kilograms per Cubic Centimeter to Kilograms per Cubic Millimeter

Kilogram 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 = kilograms per cubic centimeter × 0.001

This factor comes from each unit's defined relationship to the category's base unit: 1 kilogram per cubic centimeter equals 1000000 base units, and 1 kilogram per cubic millimeter equals 1000000000 base units, so dividing one by the other gives the direct kilogram per cubic centimeter-to-kilogram per cubic millimeter factor of 0.001.

Simple example

1 kg/cm3 × 0.001 = 0.001 kg/mm3

1 kilogram per cubic centimeter = 0.001 kilograms per cubic millimeter.

Real-world example

1,000 kg/cm3 × 0.001 = 1 kg/mm3

1,000 kilograms per cubic centimeter = 1 kilogram per cubic millimeter.

Frequently asked questions

How many kilograms per cubic millimeter are in 1 kilogram per cubic centimeter?

1 kilogram per cubic centimeter equals 0.001 kilograms per cubic millimeter, using the exact defined conversion factor rather than an estimate.

How do I convert kilogram per cubic centimeter to kilogram per cubic millimeter?

Multiply the kilogram per cubic centimeter value by 0.001. The converter above does this instantly to whatever precision you set.

How do I convert kilogram per cubic millimeter back to kilogram per cubic centimeter?

Use the reverse factor: 1 kilogram per cubic millimeter equals 1,000 kilograms per cubic centimeter. You can also use the swap control in the converter above to flip the direction instantly.

What is a kilogram per cubic centimeter?

Kilogram per Cubic Centimeter (kg/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 kilogram per cubic centimeter to kilogram per cubic millimeter conversion exact?

Yes. Both kilogram per cubic centimeter and kilogram per cubic millimeter 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.

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.
