Gas M³ to kWh Converter – UK Gas Unit Conversion Calculator
Converting gas meter readings from cubic metres (m³) to kilowatt-hours (kWh) is essential for understanding UK gas bills and energy consumption. Gas meters measure volume, but energy suppliers charge based on energy content. Our Gas M³ to kWh converter uses the official UK formula with standard calorific value (39.2 MJ/m³) and correction factor (1.02264) to provide accurate conversions for all major UK gas suppliers including British Gas, E.ON, EDF, and Octopus Energy.
m³ to kWh Calculator
Formula
kWh = (m³ × Calorific Value × Correction Factor) ÷ 3.6This official UK formula converts gas volume to energy content. We multiply m³ by calorific value (39.2 MJ/m³) and correction factor (1.02264), then divide by 3.6 to convert MJ to kWh.

Why Convert Gas M³ to kWh?
In the UK, gas meters display consumption in cubic metres (m³), but energy bills are calculated in kilowatt-hours (kWh). This conversion is essential because:
- ✓UK energy bills are legally required to show consumption in kWh for easy tariff comparison
- ✓Gas unit prices are quoted per kWh, not per m³
- ✓You can estimate your gas bill before it arrives
- ✓Compare energy suppliers accurately using kWh rates
Example Conversion
If your meter shows 100 m³ usage, this equals approximately 1,113 kWh using the UK standard formula. At 7p per kWh, your gas cost would be around £77.91 (plus standing charges).
Formula for Gas Conversion (M³ → kWh)
Official UK Gas Conversion Formula:
kWh = (m³ × Calorific Value × Correction Factor) ÷ 3.6Calorific Value
Typically 39.2 MJ/m³ in the UK
Correction Factor
Usually 1.02264 for temperature/pressure
Conversion Factor
3.6 converts MJ to kWh
Result: 1 cubic metre of natural gas ≈ 11.1 kWh (this may vary slightly by supplier and region)
Gas Cost Calculator – Estimate Your Bill
After converting m³ to kWh, you can estimate your gas bill using this simple formula:
Total Cost = (kWh × Unit Rate) + Standing ChargeExample Calculation:
- • Gas usage: 100 m³ ≈ 1,113 kWh
- • Unit rate: 7p per kWh
- • Standing charge: 30p/day (≈ £9/month)
- • Total bill: (1,113 × £0.07) + £9 = £86.91
Natural Gas Conversion Factors
Gas conversion factors vary slightly between countries and suppliers due to different gas compositions and measurement standards.
UK Standard Values
- • Calorific Value: 37.5 - 43.0 MJ/m³
- • Average: 39.2 MJ/m³
- • Correction Factor: 1.02264
- • Result: ~11.1 kWh per m³
International Variations
- • EU: 9.5 - 12.8 kWh/m³
- • US: ~10.4 kWh/m³ (1,037 BTU/ft³)
- • Canada: ~10.5 kWh/m³
- • Australia: ~10.8 kWh/m³

Frequently Asked Questions
Understanding Gas M³ to kWh Conversion in the UK
The conversion from cubic metres (m³) to kilowatt-hours (kWh) is fundamental to understanding your UK gas bill. While your gas meter measures the volume of gas consumed, energy suppliers charge based on the energy content of that gas.
This system exists because natural gas composition can vary, affecting its energy content. By converting to kWh, you pay for the actual energy you receive, not just the volume. This standardization also makes it easier to compare gas and electricity tariffs, as both are measured in kWh.
Key Benefits of Our Calculator
- •UK-Specific: Uses official UK conversion factors and formulas
- •Instant Results: No manual calculations required
- •Bill Estimation: Helps predict your gas costs
- •Supplier Comparison: Compare tariffs using kWh rates
Imperial Gas Meters
If you have an older imperial gas meter (measuring in cubic feet), first multiply your reading by 2.83 to convert to m³, then use our calculator. Some suppliers do this conversion automatically.
Final Thoughts – From M³ to kWh, Made Simple
Energy bills are complicated enough — the least we can do is make gas conversions easy. Whether you're trying to figure out "How many kWh in 1 m³ of gas?", "How to convert gas units into kWh for my bill?", or "What's my gas usage in real energy terms?", our Gas M³ to kWh Calculator has you covered.
Bookmark this page, share it with friends, and never be confused by gas bills again. Our calculator uses the most up-to-date UK conversion factors to ensure accuracy for all major gas suppliers including British Gas, E.ON, EDF, Octopus Energy, and more.
