Pool Volume Calculator

Works out how much water a swimming pool holds, in gallons, cubic feet and liters. Choose a rectangular, round or oval pool and enter the surface dimensions in feet plus the water depth; if the floor slopes, enter the shallow and deep readings and the tool averages them. A separate action turns a gallon figure into a filling time at your hose flow rate and a water bill. Measure the depth of the water rather than the height of the wall, since most pools sit several inches below the coping. Averaging the two depths is exact only when the floor slopes evenly from one end to the other.

Measurements In
Every dimension below is read in this unit, and the volume, the surface area and the average depth all come back in it.
In feet, or in metres if you chose metres above. 1 to 300 ft, which is 0.3 to 91.44 m.
In feet, or in metres if you chose metres above. 1 to 300 ft, which is 0.3 to 91.44 m.
Measure the water, not the wall. 0.5 to 30 ft, which is 0.15 to 9.14 m.
Leave blank if the floor is flat. In the same unit as the shallow end.

Water Measured In
The flow rate is read per minute in the same unit. The water price goes per 1,000 US gallons or per cubic metre, whichever you picked.
Up to 10,000,000 US gallons, which is 37,854,118 litres.
A garden hose runs roughly 8 to 17 gallons a minute, which is 30 to 64 litres a minute.
Per 1,000 US gallons, or per cubic metre on the litres setting. A cubic metre is 264 gallons, so $4.00 per 1,000 gallons is $1.06 per cubic metre. Leave it blank or at zero to skip the cost.
