About Converting Kilograms per Cubic yard to Kilograms per Imperial gallon
Kilogram per Cubic yard and Kilogram per Imperial gallon 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 Cubic yard is most often used for can be used to express the density of bulk construction materials such as gravel, soil, or aggregate — in practice, us construction and landscaping references more commonly express this as tons per cubic yard or pounds per cubic foot.
Formula
kilograms per imperial gallon = kilograms per cubic yard × 0.00594606123096
This factor comes from each unit's defined relationship to the category's base unit: 1 kilogram per cubic yard equals 1.30795061931 base units, and 1 kilogram per imperial gallon equals 219.969248299 base units, so dividing one by the other gives the direct kilogram per cubic yard-to-kilogram per imperial gallon factor of 0.00594606123096.
Simple example
1 kg/yd3 × 0.005946061231 = 0.0059460612 kg/imp gal
1 kilogram per cubic yard = 0.0059460612 kilograms per imperial gallon.
Real-world example
1,000 kg/yd3 × 0.005946061231 = 5.946061231 kg/imp gal
1,000 kilograms per cubic yard = 5.946061231 kilograms per imperial gallon.
