The maths behind it
This tool uses LPG holds about 13.6 kWh per kilogram. Days = total energy ÷ (burners × burner power × hours per day). Every intermediate value is shown on screen, so the result can be checked by hand.
The figure assumes burners at full power throughout, which almost nobody does — treat it as the shortest realistic life rather than the expected one. A cylinder emptying much faster than this is worth checking for a regulator leak, which is expensive and dangerous.
