About Converting Drams per Cubic foot to Short tons per Cup
Dram per Cubic foot and Short ton per Cup 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 cup = drams per cubic foot × 1.631843e-8
This factor comes from each unit's defined relationship to the category's base unit: 1 dram per cubic foot equals 0.0625721225545 base units, and 1 short ton per cup equals 3834445.67414 base units, so dividing one by the other gives the direct dram per cubic foot-to-short ton per cup factor of 1.631843e-8.
Simple example
1 dr/ft3 × 1.631843e-8 = 1.631843e-8 ton/cup
1 dram per cubic foot = 1.631843e-8 short tons per cup.
Real-world example
1,000 dr/ft3 × 1.631843e-8 = 0.0000163184 ton/cup
1,000 drams per cubic foot = 0.0000163184 short tons per cup.

What is a dram per cubic foot?
Dram per Cubic foot (dr/ft3) is a unit of density.
What is a short ton per cup?
Short ton per Cup (ton/cup) is a unit of density.
Is the dram per cubic foot to short ton per cup conversion exact?
Yes. Both dram per cubic foot and short ton per cup are defined by fixed standards rather than physical artifacts, so the factor of 1.631843e-8 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.
