What units does imperial mode expect?
Enter length and width in feet and depth in inches; results include cubic feet and cubic yards.
Concrete Calculator
Estimate concrete volume in cubic meters, cubic feet, and cubic yards.

Example
A metric slab 5 m long, 3 m wide, and 0.1 m deep has a volume of 1.5 cubic meters.
Calculation method
Metric mode multiplies three dimensions in meters. Imperial mode treats length and width as feet and depth as inches, then converts the volume.
Important notes
Order extra material for waste, uneven excavation, spillage, and supplier increments; confirm structural depth and mix with a qualified professional.
Frequently asked questions
Does the result include a waste allowance?
No. The displayed geometric volume has no added percentage for waste or site conditions.
Can this design a structural foundation?
No. It estimates volume only and does not determine reinforcement, strength, drainage, or safe dimensions.
