About Converting Pounds per Cubic yard to Long tons per Cubic yard
Pound per Cubic yard and Long ton 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
long tons per cubic yard = pounds per cubic yard × 0.000446428571429
This factor comes from each unit's defined relationship to the category's base unit: 1 pound per cubic yard equals 0.593276421258 base units, and 1 long ton per cubic yard equals 1328.93918362 base units, so dividing one by the other gives the direct pound per cubic yard-to-long ton per cubic yard factor of 0.000446428571429.
