Calculating The Volume of Your Pool

Square & Rectangular Pools
Length (ft) x Width (ft) x Average Depth (ft) x 6.25 = Gallons
Length (m) x Width (m) x Average Depth (m) x 1.0 = m³

Circular Pools
Diameter (ft) x Diameter (ft) x Depth (ft) x 4.9 = Gallons
Diameter (m) x Diameter (m) x Depth (m) x 0.80 = m³
