How to Calculate Swimming Pool Volume in Gallons
Here is how to figure out the Gallons in a swimming pool:
Measure the swimming pool. You will need the overall length, width and the depth in both the shallow end
and deep end.
The formulas below assume you are measuring in feet, and want results in gallons.
For a Rectangle Pool:
(Deep End + Shallow End) / 2 = Average Depth
Average Depth x Length x Width x 7.48 = Volume in Gallons
