LPG Consumption Calculator

Work out lpg consumption instantly with clear inputs, formula shown and shareable results.

About LPG Consumption Calculator

Actual gas consumption is the burner rating times duty cycle times hours, converted to kilograms at 13.8 kWh per kilogram. Duty cycle is what people miss — a hob rarely runs every burner at full, so a nominal 11 kW might average only 4 kW.

Formula

LPG consumption

kg per day = rating x duty cycle x hours / 13.8 kWh per kg

Worked example

With the default values below, LPG Consumption Calculator returns Daily consumption of 1.12. Change any input above and every figure here is recalculated in your browser.

Assumptions and limits

The result is derived only from the 4 inputs listed above. Anything not among them is not part of the calculation.
In particular, this calculator does not take inflation, tax, fees or charges or compounding frequency into account.
Figures are rounded for display to 2 decimal places, so totals built from several rounded parts can differ slightly from the unrounded arithmetic.

How these calculators are built and tested is described on the Methodology page. If a figure looks wrong, please report it.

Frequently Asked Questions

How do I estimate duty cycle?

Compare metered or weighed consumption over a week with the nameplate rating. For a domestic hob it is typically 20-40%.

Is LPG cheaper than electricity?

Per kilowatt-hour usually yes, but electric induction hobs are far more efficient at delivering heat into the pan, which narrows the gap considerably.
