About Converting Pounds per Imperial gallon to Kilograms per Cubic yard
Pound per Imperial gallon and Kilogram 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
kilograms per cubic yard = pounds per imperial gallon × 76.2845104316
This factor comes from each unit's defined relationship to the category's base unit: 1 pound per imperial gallon equals 99.7763726631 base units, and 1 kilogram per cubic yard equals 1.30795061931 base units, so dividing one by the other gives the direct pound per imperial gallon-to-kilogram per cubic yard factor of 76.2845104316.
Simple example
1 lb/imp gal × 76.28451043 = 76.28451043 kg/yd3
1 pound per imperial gallon = 76.28451043 kilograms per cubic yard.
Real-world example
1,000 lb/imp gal × 76.28451043 = 76,284.51043 kg/yd3
1,000 pounds per imperial gallon = 76,284.51043 kilograms per cubic yard.
