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 a US cup?
Eight US fluid ounces, about 236.6 ml. The "legal" cup on nutrition labels is a rounded 240 ml.
How many US cups are in a cubic yard?
One cubic yard is 3231.5844 US cups. Going the other way, one US cup is 3.0945 × 10^-4 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.
