How do you get gallons of pool?

Answer 1

You need three measurements:

1. Length in feet
2. Width in feet
3. Average depth in feet (add the shallow depth to the deep end depth and divide by 2)

Next, multiply the three measures to get the volume of the pool in cubic feet. Once you've done that, use this formula to determine gallons:

• cubic feet x 7.48 = gallons

An example: For a 36' long by 18' wide by 6' (average depth) pool:

1. 36' x 18' x 6' = 3,888 cubic feet of volume -
2. • 3,888 x 7.48 = 29,082.24 gallons

Answer 2

Calculate the volume in cubic feet:

• rectangular pool by length x width x depth
• round pool by 3.141 x radius2 x depth

Multiply cubic feet x 7.481 to get gallons.

If the pool has a sloped bottom, you will need to use the average depth in your calculation. If the pool has an irregular shape, overlay regular shapes or fractions of regular shapes to get the area or overlay a drawing of the shape with a grid and count blocks.
