How many gallons of water are in a 15-foot round above-ground pool?

Answer 1

The calculation is:

Diameter x Diameter x Depth X 5.9 = Number of Gallons

For example:

For a 15-foot round pool with a water depth of 3 ft: 15x15x3x5.9 = 3,982 gallons.

Since you did not specify the depth of the water, I will provide an answer for a couple of likely depths below.

Please note that this is the ACTUAL water depth NOT the height of the pool wall (the water is usually around 6 inchs lower than the wall height).

36 in depth: 3,982 gallons 42 inch depth: 4,646 gallons 48 inch depth: 5,310 gallons
