Methodology
Transparent calculation
BuildMeter converts every input to a consistent internal unit, applies the selected allowance, and rounds products up to whole purchasable units.
Average depth = (shallow depth + deep depth) ÷ 2. Water volume = length × width × average depth × fill percentage. Weight uses standard freshwater density.
FAQ
Pool Water Weight Calculator questions
Why is average depth used?+
For a simple uniformly sloped rectangular pool, the mean of shallow and deep depth approximates the water volume.
Does salt water weigh more?+
Yes, slightly. This calculator uses freshwater density.
Can this verify a pool structure or deck?+
No. Structural loads require project-specific engineering and support details.
