How We Calculate Volume

Geometric Formulas

A simple method of calculating pool size is the use of geometric formulas. Following are the basic formulas and calculations to determine surface areas:

A = Area
L = Length
W = Width
H = Height
r = Radius
d = Diameter
Pi = 3.142 constant

Area of a triangle: A = (L* W)/2

Area of a square or rectangle: A = L * W

Area of a circle: A = Pi * (d/2)*(d/2) OR Pi*r*r

Calculating Volume

The cubic volume can be calculated by including the depth of the pool with the surface area. For accurate calculations, the pool should be divided into various areas according to the depth.

Converting Litres and Gallons

The calculated volume is used for litres of water. To convert to gallons you multiply the volume by 7.5.

These calculations are automatically done in the form above.
