How Gas Conversion Works
Converting Metric Gas Readings (m³ to kWh):
- 1. Take your meter reading in cubic meters (m³)
- 2. Multiply by the calorific value (energy content of gas)
- 3. Multiply by the volume correction factor (1.02264)
- 4. Divide by the kWh conversion factor (3.6)
m³ × Calorific Value × 1.02264 ÷ 3.6 = kWhImperial Conversion:
- 1. Take your meter reading in cubic feet (ft³)
- 2. Convert to cubic meters (multiply by 0.0283)
- 3. Apply the same metric conversion process
- 4. Get your result in kWh
ft³ × 0.0283 × 39.2 × 1.02264 ÷ 3.6 = kWhUnderstanding how to convert gas m³ to kWh is essential for every UK household and business owner. Our comprehensive gas m³ to kWh calculator provides instant, accurate conversions using the official UK gas industry formula. Whether you're trying to understand your gas bill, calculate gas consumption, or compare energy suppliers, this m³ to kWh calculator is your go-to tool for all gas unit conversions.
The UK gas billing system requires converting natural gas m³ to kWh because while your gas meter measures volume in cubic metres, energy suppliers charge based on the energy content measured in kilowatt-hours. This gas conversion from m³ to kWh accounts for the varying energy content of natural gas, ensuring you pay for the actual energy you consume rather than just the volume.
Our advanced gas units to kWh calculator uses the latest UK conversion factors, including the standard calorific value of 39.2 MJ/m³ and the volume correction factor of 1.02264. This ensures your gas meter reading to kWh conversion is accurate and compliant with UK energy regulations. The tool also functions as a comprehensive gas bill calculator, helping you estimate costs and understand your energy consumption patterns.
Whether you need to convert gas m³ to kWh for bill verification, energy auditing, or supplier comparison, our calculator provides professional-grade accuracy. The tool supports both metric and imperial gas meters, making it suitable for all UK properties. Additionally, our gas consumption calculator helps you track usage patterns and identify opportunities for energy savings.

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
Varies by region: 37.5-43.0 MJ/m³
Correction Factor
Usually 1.02264 for temperature/pressure
Adjusts for standard conditions
Conversion Factor
3.6 converts MJ to kWh
Standard energy unit conversion
Result: 1 cubic metre of natural gas ≈ 11.1 kWh (this may vary slightly by supplier and region based on actual gas composition)
Understanding the Variables
The calorific value represents the energy content of gas and varies based on the source and composition of natural gas. The correction factor adjusts the volume to standard temperature and pressure conditions. These factors ensure accurate billing regardless of seasonal variations or regional differences in gas composition.

Gas Cost Calculator – Estimate Your Bill
After using our gas m³ to kWh calculator to convert your meter reading, you can estimate your gas bill using current UK energy prices. This gas cost calculator UK helps you understand your energy expenses and budget effectively.
Gas Bill Calculation Formula:
Total Cost = (kWh × Unit Rate) + (Days × Standing Charge)Current Average UK Rates (2024):
- • Unit Rate: 6-8p per kWh
- • Standing Charge: 25-30p per day
- • VAT: 5% on total bill
Example Calculation:
- • Usage: 100 m³ = 1,110 kWh
- • Energy cost: 1,110 × £0.07 = £77.70
- • Standing charge: 30 days × £0.28 = £8.40
- • Total: £86.10 + VAT = £90.41

Frequently Asked Questions
How to convert m³ to kWh in the UK?
To convert m³ to kWh in the UK, use the official formula: kWh = (m³ × 39.2 × 1.02264) ÷ 3.6. This accounts for the standard UK calorific value (39.2 MJ/m³) and volume correction factor (1.02264). Our m³ to kWh calculator UK tool automates this calculation for instant, accurate results.
For quick estimates, multiply your m³ reading by 11.1 to get approximate kWh. However, for precise billing calculations, always use the exact calorific value provided by your gas supplier, which can be found on your gas bill or supplier's website.
How many kWh is 1 cubic meter of gas?
In the UK, 1 cubic meter of natural gas equals approximately 11.1 kWh using standard conversion factors. This value can vary slightly (typically between 10.8-11.4 kWh) depending on the actual calorific value of gas in your area, which varies based on the source and composition of the natural gas supply.
The exact conversion factor is printed on your gas bill and updated regularly by your supplier. Use our cubic meters to kWh calculator for the most accurate conversions based on current UK standards.
Why is my gas bill in kWh instead of m³?
UK gas bills show consumption in kWh because you're paying for the energy content of the gas, not just its volume. Natural gas composition varies, affecting its energy content. By billing in kWh, suppliers ensure you pay for the actual energy you receive, making pricing fair and consistent regardless of gas composition variations.
This system also enables easy comparison between gas and electricity tariffs, both measured in kWh. It's a legal requirement under UK energy regulations to display consumption in kWh for transparency and consumer protection.
How to convert kWh back to m³?
To convert kWh to m³ gas, reverse the standard formula: m³ = (kWh × 3.6) ÷ (39.2 × 1.02264). For quick estimates, divide kWh by 11.1. Our kWh to m³ calculator provides instant bidirectional conversion for both directions of this calculation.
This reverse calculation is useful for estimating how much gas volume you'll need for a specific energy requirement, or for converting energy consumption data back to physical gas volumes for technical applications.
How do British Gas calculate kWh from meter readings?
British Gas and other UK suppliers calculate gas consumption by taking your current meter reading, subtracting the previous reading to get m³ used, then applying the standard UK conversion formula. They use the calorific value specific to your gas supply area, which is updated regularly and shown on your bill.
The process involves: (Current Reading - Previous Reading) × Calorific Value × 1.02264 ÷ 3.6 = kWh consumed. This standardized approach ensures consistent billing across all UK gas suppliers and complies with Ofgem regulations.
Is the conversion different for natural gas vs LPG?
Yes, LPG (Liquefied Petroleum Gas) has a much higher energy content than natural gas. LPG typically contains about 93-95 MJ/m³ compared to natural gas at 39.2 MJ/m³. This means 1 m³ of LPG equals approximately 26-27 kWh, more than double that of natural gas.
However, LPG is typically sold by weight (kg) rather than volume (m³) for domestic use. If you have an LPG meter, always check with your supplier for the specific conversion factors, as these can vary significantly from natural gas calculations.
What is the calorific value used in gas billing?
The calorific value used in UK gas billing typically ranges from 37.5 to 43.0 MJ/m³, with an average of 39.2 MJ/m³. This value represents the energy content of the gas and varies based on the source and composition of the natural gas supply. Your exact calorific value is shown on your gas bill and updated regularly by your supplier.
Gas suppliers obtain calorific values from the National Grid Gas Transmission, which monitors gas quality across the UK network. These values are measured continuously and averaged over billing periods to ensure accurate energy billing.
How to calculate gas usage from meter readings?
To calculate gas usage from meter readings: 1) Take your current meter reading, 2) Subtract your previous reading to get m³ consumed, 3) Use our gas consumption calculator to convert to kWh, 4) Multiply by your unit rate to get cost. For imperial meters (ft³), first multiply by 2.83 to convert to m³.
Regular meter readings help you monitor consumption patterns, identify unusual usage, and budget for energy costs. Many smart meters automatically send readings to suppliers, but manual readings are still useful for personal monitoring and verification.
