WATER / RECTANGULAR POOL
Estimate rectangular swimming-pool water volume from length, width, average depth, and fill percentage in litres and US gallons.
Use boundary
Length, width, and average depth create cubic metres; fill level scales the result before litre and gallon conversion.
Pool volume = length x width x average depth x fill fraction.

Steps, benches, curves, overflow level, displacement, and sloped-floor averaging can materially change actual water volume.
Planning and fitness outputs are estimates. Confirm measurements, product specifications, site conditions, health context, and professional requirements before making purchasing, training, medication, or care decisions.
