How the concrete calculator works
The concrete calculator helps you estimate results using the assumptions and values you provide. Review the formula and example before relying on the result.
Formula and assumptions
Rectangular volume = length × width × depth. Keep all dimensions in the same unit before converting volume.
Example
A 2 m × 3 m × 0.1 m slab requires 0.6 cubic metres before waste allowance.
