What is a cubic yard?
Twenty-seven cubic feet, or 764.55 litres. Concrete, topsoil and aggregate are all ordered by it in the US, and it is the unit a truck is measured in.
What is an imperial gallon?
Exactly 4.54609 liters since 1985, and the reason UK and US fuel economy figures cannot be compared: it is 20% larger than the US gallon, so 40 mpg in Britain is about 33 mpg in America on the same car.
How many imperial gallons are in a cubic yard?
One cubic yard is 168.17856 imperial gallons. Going the other way, one imperial gallon is 0.0059460612 cubic yards. Both figures come from the same defined relation rather than from a measurement, which is why they are the same today as they were in 1959.
