About Converting Stones per Cubic Millimeter to Kilograms per Cubic Centimeter

Stone per Cubic Millimeter and Kilogram per Cubic Centimeter 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 centimeter = stones per cubic millimeter × 6350.29318

This factor comes from each unit's defined relationship to the category's base unit: 1 stone per cubic millimeter equals 6350293180 base units, and 1 kilogram per cubic centimeter equals 1000000 base units, so dividing one by the other gives the direct stone per cubic millimeter-to-kilogram per cubic centimeter factor of 6350.29318.

Simple example

1 st/mm3 × 6350.29318 = 6,350.29318 kg/cm3

1 stone per cubic millimeter = 6,350.29318 kilograms per cubic centimeter.

Real-world example

1,000 st/mm3 × 6350.29318 = 6,350,293.18 kg/cm3

1,000 stones per cubic millimeter = 6,350,293.18 kilograms per cubic centimeter.

Frequently asked questions

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

1 stone per cubic millimeter equals 6,350.29318 kilograms per cubic centimeter, using the exact defined conversion factor rather than an estimate.

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

Multiply the stone per cubic millimeter value by 6350.29318. The converter above does this instantly to whatever precision you set.

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

Use the reverse factor: 1 kilogram per cubic centimeter equals 0.000157473 stones per cubic millimeter. You can also use the swap control in the converter above to flip the direction instantly.

What is a stone per cubic millimeter?

Stone per Cubic Millimeter (st/mm3) is a unit of density.

What is a kilogram per cubic centimeter?

Kilogram per Cubic Centimeter (kg/cm3) is a unit of density.

Is the stone per cubic millimeter to kilogram per cubic centimeter conversion exact?

Yes. Both stone per cubic millimeter and kilogram per cubic centimeter are defined by fixed standards rather than physical artifacts, so the factor of 6350.29318 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.
