Units explained
Cubic Yard
A cubic yard is the volume of a cube one yard on a side (0.764555 m³).
Derived by cubing the international yard (0.9144 m, fixed 1959).
The standard US/UK unit for concrete, soil and bulk landscaping.
1959 yard agreement.
US Quart
A US liquid quart is one quarter of a US gallon (0.946352946 L).
From the Latin quartus, a quarter of a gallon.
Used for milk, oil and household liquids in the US.
English customary.
