About Converting Kilograms per Imperial gallon to Kilograms per Cubic yard
Kilogram 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. 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
kilograms per cubic yard = kilograms per imperial gallon × 168.178557394
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 kilogram per cubic yard equals 1.30795061931 base units, so dividing one by the other gives the direct kilogram per imperial gallon-to-kilogram per cubic yard factor of 168.178557394.
Simple example
1 kg/imp gal × 168.1785574 = 168.1785574 kg/yd3
1 kilogram per imperial gallon = 168.1785574 kilograms per cubic yard.
Real-world example
1,000 kg/imp gal × 168.1785574 = 168,178.5574 kg/yd3
1,000 kilograms per imperial gallon = 168,178.5574 kilograms per cubic yard.
