How big is your pool

Properly sizing your pool is critical in determining a chemical program. This allows you to use the proper amounts of chemicals to keep your water CRYSTAL CLEAR AND HEALTHY.

Formulae:

Rectangle Area = length x width

Circle Area = 3.141 radius x radius

or Circle Area = .78 x diameter x diameter

Oval Area = .78 x length x width

Volumes in liters are thus:

**Rectangular:**Metric Length x Metric Width x Average Metric Depth x 1000 = Total Liters**Circular:**Diameter x Diameter x Average Depth x 780 = Total Liters**Oval:**Long Diameter x Short Diameter x Average Depth x 780 = Total Liters

Metric is simple.

- A liter of water weighs a kilogram.
- A cubic meter of water weighs a metric ton and is 1000 liters.
- A milliliter of water weighs a gram.
