Methodology
Transparent calculation
BuildMeter converts every input to a consistent internal unit, applies the selected allowance, and rounds products up to whole purchasable units.
Concrete volume = length × width × thickness × section count. The allowance is applied before ready-mix conversion and full-bag rounding.
