How Gas and Energy Conversions Work

Understanding Gas M³ to kWh Conversion

The most common conversion UK users need is from cubic meters (m³) of gas to kilowatt-hours (kWh). This conversion is essential for understanding your gas bill, as suppliers charge per kWh but your meter measures in m³.

The conversion formula uses three key factors:

  1. Volume (m³): Your meter reading in cubic meters
  2. Calorific Value (CV): Energy content per cubic meter (typically 39.5 MJ/m³ in the UK)
  3. Conversion Factor: 1.02264 (adjusts for temperature and pressure) ÷ 3.6 (converts MJ to kWh)

Standard Formula: kWh = m³ × 39.5 × 1.02264 ÷ 3.6 ≈ m³ × 10.55

For quick calculations, multiply your m³ reading by 10.55 to get kWh. This is the standard UK conversion factor used by most energy suppliers.

Imperial vs Metric Gas Meters

UK homes may have either metric (m³) or imperial (ft³) gas meters:

  • Metric meters: Read directly in cubic meters (m³)
  • Imperial meters: Read in cubic feet (ft³) - multiply by 2.83 to get m³, then by 10.55 to get kWh

Frequently Asked Questions

How do I convert gas m³ to kWh in the UK?

To convert gas cubic meters (m³) to kilowatt-hours (kWh) in the UK, multiply your m³ reading by 10.55. This uses the standard UK calorific value of 39.5 MJ/m³. For example: 100 m³ × 10.55 = 1,055 kWh. This is the conversion factor used by most UK energy suppliers.

What is the calorific value of natural gas in the UK?

The standard calorific value (CV) for natural gas in the UK is 39.5 MJ/m³ (megajoules per cubic meter), which equals 10.55 kWh/m³ (kilowatt-hours per cubic meter). However, the actual CV can vary slightly between regions and seasons, typically ranging from 38.0 to 41.0 MJ/m³. Your energy supplier will use the specific CV for your area on your bill.

How do I read my gas meter to calculate kWh?

For a metric meter (m³): Read the numbers from left to right, ignoring any red numbers. Subtract your previous reading to find usage. Multiply by 10.55 to get kWh. For an imperial meter (ft³): Read the numbers, subtract previous reading, multiply by 2.83 (to get m³), then by 10.55 to get kWh. Most UK meters installed after 1995 are metric.

Why do energy suppliers charge in kWh but my meter shows m³?

Energy suppliers charge in kWh (kilowatt-hours) because it represents the actual energy content you consume, which is what you're paying for. Your meter measures volume (m³) because it's mechanical and easier to measure volume flow. The conversion accounts for the energy content (calorific value) of the gas, which can vary. This ensures fair pricing based on energy content, not just volume.

What's the difference between m³ and Nm³?

m³ (cubic meter) measures volume at actual conditions, while Nm³ (normal cubic meter) measures volume at standard conditions (0°C, 1 atmosphere pressure). Nm³ is used for consistency in industrial applications. For UK domestic gas, the difference is minimal and both are approximately equal when using the standard conversion factor of 10.55 kWh/m³.

How accurate are these conversion calculators?

Our calculators use official UK conversion factors and are accurate to 4 decimal places. We use the standard calorific value of 39.5 MJ/m³ (10.55 kWh/m³) and the temperature/pressure correction factor of 1.02264. These are the same factors used by major UK energy suppliers. However, your supplier may use slightly different regional values, which can cause minor variations.
