Construction Calculators

Concrete Calculator – Volume & Material Estimate

Calculate concrete volume needed for slabs, footings, columns, and walls.

Length (ft)

Width (ft)

Thickness (inches)

Concrete Calculator Formula

Volume (cu ft) = Length × Width × (Thickness in inches / 12)

Cubic Yards = Cubic Feet / 27

Slab: 12ft × 12ft × 6 inches

Cu ft = 12 × 12 × 0.5 = 72 cu ft

Cu yd = 72 / 27 = 2.67 cu yd
