About Converting Long tons per Cubic foot to Pounds per Cubic yard
Long ton per Cubic foot and Pound per Cubic yard 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 cubic yard = long tons per cubic foot × 60480
This factor comes from each unit's defined relationship to the category's base unit: 1 long ton per cubic foot equals 35881.3579577 base units, and 1 pound per cubic yard equals 0.593276421258 base units, so dividing one by the other gives the direct long ton per cubic foot-to-pound per cubic yard factor of 60480.
Simple example
1 long ton/ft3 × 60480 = 60,480 lb/yd3
1 long ton per cubic foot = 60,480 pounds per cubic yard.
Real-world example
1,000 long ton/ft3 × 60480 = 60,480,000 lb/yd3
1,000 long tons per cubic foot = 60,480,000 pounds per cubic yard.

What is a long ton per cubic foot?
Long ton per Cubic foot (long ton/ft3) is a unit of density.
What is a pound per cubic yard?
Pound per Cubic yard (lb/yd3) is a unit of density.
Is the long ton per cubic foot to pound per cubic yard conversion exact?
Yes. Both long ton per cubic foot and pound per cubic yard are defined by fixed standards rather than physical artifacts, so the factor of 60480 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.
