About Converting Pounds per Cubic Centimeter to Long tons per Cubic yard
Pound per Cubic Centimeter 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 centimeter × 341.319133029
This factor comes from each unit's defined relationship to the category's base unit: 1 pound per cubic centimeter equals 453592.37 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 centimeter-to-long ton per cubic yard factor of 341.319133029.
Simple example
1 lb/cm3 × 341.319133 = 341.319133 long ton/yd3
1 pound per cubic centimeter = 341.319133 long tons per cubic yard.
Real-world example
1,000 lb/cm3 × 341.319133 = 341,319.133 long ton/yd3
1,000 pounds per cubic centimeter = 341,319.133 long tons per cubic yard.
