About Converting Pounds per Cubic foot to Short tons per Gallon
Pound per Cubic foot 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. Pound per Cubic foot is most often used for us construction material density specs (concrete, soil, lumber, insulation).
Formula
short tons per gallon = pounds per cubic foot × 0.0000668402777778
This factor comes from each unit's defined relationship to the category's base unit: 1 pound per cubic foot equals 16.018463374 base units, and 1 short ton per gallon equals 239652.854634 base units, so dividing one by the other gives the direct pound per cubic foot-to-short ton per gallon factor of 0.0000668402777778.
Simple example
1 lb/ft3 × 0.00006684027778 = 0.0000668403 ton/gal
1 pound per cubic foot = 0.0000668403 short tons per gallon.
Real-world example
1,000 lb/ft3 × 0.00006684027778 = 0.0668402778 ton/gal
1,000 pounds per cubic foot = 0.0668402778 short tons per gallon.
