Pool volume

—

Uses internal rectangular dimensions and a uniformly sloping floor. Steps, benches, curved walls and changes in water level are not modeled.

Formula

Use V = lw(a+b)/2. l and w are rectangular pool length and width; a and b are shallow and deep depths, all in m. V is in m³, assuming a uniformly sloping floor.

Scope and limitations

Uses internal rectangular dimensions and a uniformly sloping floor. Steps, benches, curved walls and changes in water level are not modeled.

Inputs are checked for missing values and allowed ranges. A result outside the finite numeric range is not displayed. Rounding affects display, while the calculation uses the model’s numeric precision.

Check your units and assumptions before relying on a result. Changing a label does not convert a currency or physical unit.
