Concrete Calculator

Calculate the volume of concrete for a rectangular slab.

* Length & Width in feet; Thickness in inches.

Step 1: Enter Dimensions

Enter the length in feet.

Enter the width in feet.

Enter the thickness in inches.

Formula:
Volume (ft³) = Length (ft) × Width (ft) × (Thickness (in) ÷ 12)
Volume (yd³) = Volume (ft³) ÷ 27
Volume (m³) = Volume (ft³) × 0.0283
