About Converting Pounds per Cup to Short tons per Gallon
Pound 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 = pounds per cup × 0.008
This factor comes from each unit's defined relationship to the category's base unit: 1 pound per cup equals 1917.22283707 base units, and 1 short ton per gallon equals 239652.854634 base units, so dividing one by the other gives the direct pound per cup-to-short ton per gallon factor of 0.008.
Simple example
1 lb/cup × 0.008 = 0.008 ton/gal
1 pound per cup = 0.008 short tons per gallon.
Real-world example
1,000 lb/cup × 0.008 = 8 ton/gal
1,000 pounds per cup = 8 short tons per gallon.

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