See the kWh equivalent of a gas meter reading, or reverse a supplier's kWh figure back into approximate m³. Use the default assumptions for a quick estimate or open the advanced settings to match the exact figures shown on your bill.
m³
Converted to kWh:
0 kWh
- Formula used
- m³ × calorific value × volume correction factor ÷ 3.6
- Calorific value
- 39.5 MJ/m³
- Volume correction factor
- 1.02264
- How do I convert m3 to kWh for a gas bill?
- Enter the gas volume in cubic metres and the converter applies the standard UK billing formula using calorific value, a volume correction factor, and division by 3.6 to reach kWh. If your supplier has already done that step, switch the converter direction and work backwards instead.
- Can I change the calorific value or volume correction factor?
- Open advanced settings if your bill shows a different calorific value or correction factor and you want the conversion to match your supplier more closely.
- What figures do most UK household bills use?
- The volume correction factor is normally 1.02264. The calorific value varies, so suppliers bill using an average figure for your area and billing period. This converter starts with a representative default of 39.5 MJ/m³, but use the value printed on your bill if you want the closest match.
- Will this work for an imperial gas meter?
- This converter is for metric gas readings in cubic metres (m³). If your meter is marked in cubic feet or ft³, the result will not match directly. Use the kWh figure from your bill, or convert the imperial reading into cubic metres before using this tool.
- Where can I estimate the full cost of my gas bill?
- Use the Gas Bill Calculator if you want to turn gas usage into an estimated bill including unit rates, standing charges, and VAT.
