About Converting Drams per Cup to Short tons per Gallon
Dram per Cup and Short ton per Gallon 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 gallon = drams per cup × 0.00003125
This factor comes from each unit's defined relationship to the category's base unit: 1 dram per cup equals 7.48915170731 base units, and 1 short ton per gallon equals 239652.854634 base units, so dividing one by the other gives the direct dram per cup-to-short ton per gallon factor of 0.00003125.
Simple example
1 dr/cup × 0.00003125 = 0.00003125 ton/gal
1 dram per cup = 0.00003125 short tons per gallon.
Real-world example
1,000 dr/cup × 0.00003125 = 0.03125 ton/gal
1,000 drams per cup = 0.03125 short tons per gallon.

What is a dram per cup?
Dram per Cup (dr/cup) is a unit of density.
What is a short ton per gallon?
Short ton per Gallon (ton/gal) is a unit of density.
Is the dram per cup to short ton per gallon conversion exact?
Yes. Both dram per cup and short ton per gallon are defined by fixed standards rather than physical artifacts, so the factor of 0.00003125 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.
