How to Read and Verify the Pool Volume Calculator Output

The output panel reports the exact result derived from Pool plan shape, Length or diameter (m), Width or minor diameter (m) alongside any unit or formatting notes.

The result is the plan area and estimated water volume. Estimate a pool from its plan shape and average water depth.

Ellipse dimensions are full axes, and average depth is supplied rather than surveyed.

Numerical output shows up to 12 significant digits. Floating-point arithmetic and display rounding can affect the last digits.

Example input
Pool plan shape = Rectangle; Length or diameter (m) = 10; Width or minor diameter (m) = 5; Supplied average water depth (m) = 1.5
Example output
Plan area: 50 m2 Estimated volume: 75 m3 Estimated volume: 75000 L
