About Converting Picograms per Cubic Millimeter to Short tons per Cubic foot
Picogram 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 = picograms per cubic millimeter × 3.121398e-11
This factor comes from each unit's defined relationship to the category's base unit: 1 picogram per cubic millimeter equals 0.000001 base units, and 1 short ton per cubic foot equals 32036.9267479 base units, so dividing one by the other gives the direct picogram per cubic millimeter-to-short ton per cubic foot factor of 3.121398e-11.
Simple example
1 pg/mm3 × 3.121398e-11 = 3.121398e-11 ton/ft3
1 picogram per cubic millimeter = 3.121398e-11 short tons per cubic foot.
Real-world example
1,000 pg/mm3 × 3.121398e-11 = 3.121398e-8 ton/ft3
1,000 picograms per cubic millimeter = 3.121398e-8 short tons per cubic foot.

Frequently asked questions
How many short tons per cubic foot are in 1 picogram per cubic millimeter?
1 picogram per cubic millimeter equals 3.121398e-11 short tons per cubic foot, using the exact defined conversion factor rather than an estimate.
How do I convert picogram per cubic millimeter to short ton per cubic foot?
Multiply the picogram per cubic millimeter value by 3.121398e-11. The converter above does this instantly to whatever precision you set.
How do I convert short ton per cubic foot back to picogram per cubic millimeter?
Use the reverse factor: 1 short ton per cubic foot equals 32,036,926,750 picograms per cubic millimeter. You can also use the swap control in the converter above to flip the direction instantly.
What is a picogram per cubic millimeter?
Picogram per Cubic Millimeter (pg/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 picogram per cubic millimeter to short ton per cubic foot conversion exact?
Yes. Both picogram per cubic millimeter and short ton per cubic foot are defined by fixed standards rather than physical artifacts, so the factor of 3.121398e-11 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.
