Calculation Formulas
Amount Conversions Grams to Kilos - grams ÷1000 = Kilos Millilitres to Litres - millilitres ÷1000 = Litres
Distance Conversions Feet to Metres - feet ÷ 3.28 = Metres
Surface Area Rectangle / Square - Length x Width = Square Metre Circle - pi (3.14) x radius x radius = Square Metre ( radius = diameter ÷ 2)
Pool Volume Surface Area x Average Depth x 1000 = Litres (1 m3 = 1000 L.) Average Depth = (shallow depth + deep depth) ÷ 2
Calculating Litres in 1 Centimetre of Depth 1 metre = 100 centimetres 1cm ÷ 100cm = .01 (represents 1 cm of Depth / centimetre) Surface Area x 0.01  x 1000 = Litres
Breakpoint Chlorination CC = TC - FC Breakpoint Level = CC X 10 - Starting FC
Turnover Rate Pool Volume ÷ Flow Rate ÷ 60 = Hours
Flow Rate Pool Volume ÷ Turnover Rate ÷ 60 min/hour = Litres Per Minute (LPM)
Filter Area Flow Rate ÷ Filter Media Rate = Metres Squared
Calculating Kilojoules vs Temperature Rise Volume x 4.18 x degrees raised = Kilojoules 4.18 = the quantity of heat needed to raise water 1 degree
Spa Dumping Spa Volume ÷ 11.34 ÷ average bathers/day = Days
