By Santaji GadepatilinUpdated October 27, 2026
How long an LPG cylinder lasts depends on its gas weight and how much gas your burners use each day. This free LPG gas cylinder duration calculator solves for whichever value you leave blank and shows the formula and steps.
How to use the LPG gas cylinder duration calculator
Enter the gas weight in the cylinder, burner hours per day and the burner’s consumption. Daily use and the number of days are calculated.
Example

Burner consumption
A typical domestic burner uses about 150–250 g of LPG per hour on high flame. Small burners and simmer settings use much less. Rating plates often list consumption in g/h or kW (1 kW ≈ 75–80 g/h of LPG).
Saving gas
- Use lids on pots — cooking without a lid uses noticeably more gas.
- Match the pan size to the burner so flames do not lick up the sides.
- Use a pressure cooker for rice, dal and pulses.
- Soak beans and grains before cooking.
- Keep burners clean for a blue flame; a yellow flame wastes gas.
Safety
Check the hose and regulator regularly for cracks, turn off the regulator when not in use and never test for leaks with a flame — use soapy water.
