About Converting Kilograms per Cubic Millimeter to Short tons per Cubic foot
Kilogram per Cubic Millimeter and Short ton per Cubic foot 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
short tons per cubic foot = kilograms per cubic millimeter × 31213.9802881
This factor comes from each unit's defined relationship to the category's base unit: 1 kilogram per cubic millimeter equals 1000000000 base units, and 1 short ton per cubic foot equals 32036.9267479 base units, so dividing one by the other gives the direct kilogram per cubic millimeter-to-short ton per cubic foot factor of 31213.9802881.
Simple example
1 kg/mm3 × 31213.98029 = 31,213.98029 ton/ft3
1 kilogram per cubic millimeter = 31,213.98029 short tons per cubic foot.
Real-world example
1,000 kg/mm3 × 31213.98029 = 31,213,980.29 ton/ft3
1,000 kilograms per cubic millimeter = 31,213,980.29 short tons per cubic foot.

Frequently asked questions
How many short tons per cubic foot are in 1 kilogram per cubic millimeter?
1 kilogram per cubic millimeter equals 31,213.98029 short tons per cubic foot, using the exact defined conversion factor rather than an estimate.
How do I convert kilogram per cubic millimeter to short ton per cubic foot?
Multiply the kilogram per cubic millimeter value by 31213.98029. The converter above does this instantly to whatever precision you set.
How do I convert short ton per cubic foot back to kilogram per cubic millimeter?
Use the reverse factor: 1 short ton per cubic foot equals 0.0000320369 kilograms per cubic millimeter. You can also use the swap control in the converter above to flip the direction instantly.
What is a kilogram per cubic millimeter?
Kilogram per Cubic Millimeter (kg/mm3) is a unit of density.
What is a short ton per cubic foot?
Short ton per Cubic foot (ton/ft3) is a unit of density.
Is the kilogram per cubic millimeter to short ton per cubic foot conversion exact?
Yes. Both kilogram per cubic millimeter and short ton per cubic foot are defined by fixed standards rather than physical artifacts, so the factor of 31213.98029 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.
