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 Cup
A US customary cup is one sixteenth of a US gallon (236.588 mL).
Standardized for American cooking; distinct from the 240 mL US legal cup and the 250 mL metric cup.
The standard US cooking-volume unit in recipes.
US customary cooking measure.
