concrete volume calculator
Concrete Calculator
Estimate the volume of a simple rectangular concrete pour before ordering material.
How it works
Cubic metres = length × width × depth in metres. The calculator converts centimetres of depth to metres for you.
Three practical tips
- Measure several points if the base is uneven.
- Allow a sensible margin for spillage and variation.
- For structural work, follow the design and supplier guidance.
Does this include an allowance for waste?
No. It returns geometric volume; add the contingency recommended for your site and supplier.
