About Converting Kilograms per Imperial gallon to Pounds per Cubic yard
Kilogram per Imperial gallon 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. Kilogram per Imperial gallon is most often used for can be used to express liquid density in uk/commonwealth contexts that reference the imperial gallon — in practice, kilograms per liter is the more commonly seen metric density unit even in these regions.
Formula
pounds per cubic yard = kilograms per imperial gallon × 370.770252141
This factor comes from each unit's defined relationship to the category's base unit: 1 kilogram per imperial gallon equals 219.969248299 base units, and 1 pound per cubic yard equals 0.593276421258 base units, so dividing one by the other gives the direct kilogram per imperial gallon-to-pound per cubic yard factor of 370.770252141.
Simple example
1 kg/imp gal × 370.7702521 = 370.7702521 lb/yd3
1 kilogram per imperial gallon = 370.7702521 pounds per cubic yard.
Real-world example
1,000 kg/imp gal × 370.7702521 = 370,770.2521 lb/yd3
1,000 kilograms per imperial gallon = 370,770.2521 pounds per cubic yard.
