About Converting Short tons per Gallon to Pounds per Cup
Short ton per Gallon and Pound 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
pounds per cup = short tons per gallon × 125
This factor comes from each unit's defined relationship to the category's base unit: 1 short ton per gallon equals 239652.854634 base units, and 1 pound per cup equals 1917.22283707 base units, so dividing one by the other gives the direct short ton per gallon-to-pound per cup factor of 125.
Simple example
1 ton/gal × 125 = 125 lb/cup
1 short ton per gallon = 125 pounds per cup.
Real-world example
1,000 ton/gal × 125 = 125,000 lb/cup
1,000 short tons per gallon = 125,000 pounds per cup.

Frequently asked questions
How many pounds per cup are in 1 short ton per gallon?
1 short ton per gallon equals 125 pounds per cup, using the exact defined conversion factor rather than an estimate.
How do I convert short ton per gallon to pound per cup?
Multiply the short ton per gallon value by 125. The converter above does this instantly to whatever precision you set.
How do I convert pound per cup back to short ton per gallon?
Use the reverse factor: 1 pound per cup equals 0.008 short tons per gallon. You can also use the swap control in the converter above to flip the direction instantly.
What is a short ton per gallon?
Short ton per Gallon (ton/gal) is a unit of density.
What is a pound per cup?
Pound per Cup (lb/cup) is a unit of density.
Is the short ton per gallon to pound per cup conversion exact?
Yes. Both short ton per gallon and pound per cup are defined by fixed standards rather than physical artifacts, so the factor of 125 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.
