Round / Circular Pool Volume

The Round / Circular calculator figures out the total water volume of any pool with a circular shape. It uses the standard industry formula based on the pool's diameter and depth.

Drag the slider to compare the input form and the calculated result.

The Formula

Diameter × Diameter × Depth × 5.9 = Volume in Gallons

The 5.9 multiplier accounts for the circular shape (derived from π ÷ 4 × 7.48). FlowBeacon applies this automatically — you just enter your measurements.
