About Converting Milligrams per Gallon to Short tons per Cup
Milligram per Gallon 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 = milligrams per gallon × 6.889446e-11
This factor comes from each unit's defined relationship to the category's base unit: 1 milligram per gallon equals 0.000264172052358 base units, and 1 short ton per cup equals 3834445.67414 base units, so dividing one by the other gives the direct milligram per gallon-to-short ton per cup factor of 6.889446e-11.
Simple example
1 mg/gal × 6.889446e-11 = 6.889446e-11 ton/cup
1 milligram per gallon = 6.889446e-11 short tons per cup.
Real-world example
1,000 mg/gal × 6.889446e-11 = 6.889446e-8 ton/cup
1,000 milligrams per gallon = 6.889446e-8 short tons per cup.

What is a milligram per gallon?
Milligram per Gallon (mg/gal) 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 milligram per gallon to short ton per cup conversion exact?
Yes. Both milligram per gallon and short ton per cup are defined by fixed standards rather than physical artifacts, so the factor of 6.889446e-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.
