About Converting Grams per Cubic Millimeter to Short tons per Cubic foot
Gram 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 = grams per cubic millimeter × 31.2139802881
This factor comes from each unit's defined relationship to the category's base unit: 1 gram per cubic millimeter equals 1000000 base units, and 1 short ton per cubic foot equals 32036.9267479 base units, so dividing one by the other gives the direct gram per cubic millimeter-to-short ton per cubic foot factor of 31.2139802881.
Simple example
1 g/mm3 × 31.21398029 = 31.21398029 ton/ft3
1 gram per cubic millimeter = 31.21398029 short tons per cubic foot.
Real-world example
1,000 g/mm3 × 31.21398029 = 31,213.98029 ton/ft3
1,000 grams per cubic millimeter = 31,213.98029 short tons per cubic foot.

Multiply the gram per cubic millimeter value by 31.21398029. The converter above does this instantly to whatever precision you set.
How do I convert short ton per cubic foot back to gram per cubic millimeter?
Use the reverse factor: 1 short ton per cubic foot equals 0.0320369268 grams per cubic millimeter. You can also use the swap control in the converter above to flip the direction instantly.
What is a gram per cubic millimeter?
Gram per Cubic Millimeter (g/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 gram per cubic millimeter to short ton per cubic foot conversion exact?
Yes. Both gram per cubic millimeter and short ton per cubic foot are defined by fixed standards rather than physical artifacts, so the factor of 31.21398029 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.
