Frequently Asked Questions

How do I calculate concrete volume for a rectangular slab?

Enter the length, width, and thickness of the slab. The calculator multiplies these dimensions to give the volume in your chosen unit.

How do I calculate concrete for a circular footing?

Select the Circle shape, enter diameter and depth. The calculator uses the circle area formula π × r² and multiplies by depth to compute the volume.

What is the standard weight of concrete?

Standard reinforced concrete weighs approximately 2400 kg/m³ (150 lb/ft³). This calculator uses that density to estimate the total weight of your concrete pour.

Is the Concrete Volume Calculator free?

Yes. This Kod5 tool runs in the browser, requires no installation, and is free to use.
