Does this calculator include wastage?
No. Add 5–10% extra on site depending on formwork complexity and spillage.
Concrete Volume Calculator
Calculate concrete volume for rectangular pours from length, width, and height.
Concrete Volume Calculator Formula
- Convert Dimensions
Convert length, width, and height to metres when ft is selected - Concrete Volume
Length × Width × Height - Supporting Metrics
Convert m³ to ft³ and litres for planning
Assumptions
- The pour is treated as a rectangular prism with uniform depth.
- Foot measurements are converted to metres before volume calculation.
- Results exclude wastage, spillage, and sub-base preparation.
Frequently Asked Questions
Can I use feet for all dimensions?
Yes. Select ft as the unit and each dimension is converted internally before calculating volume.
How is concrete volume different from cement quantity?
This tool returns total concrete volume. Use the Cement Calculator to estimate bags and mix materials for a given grade.
