How to Estimate Concrete

Concrete is typically measured by volume. In the US, it is sold by the cubic yard, while internationally it is measured in cubic meters.

Estimation Formula:

Volume = Length × Width × Thickness

Note: Remember to convert all measurements to the same unit before multiplying. For cubic yards, divide the total cubic feet by 27.
