What’s the volume correction factor when converting gas units to kWh?

The volume correction factor is used to consider the temperature, pressure and atmospheric conditions at a property. This factor is typically 1.02264 unless your property has unusual atmospheric conditions. 

How to convert gas usage to kWh

  1. Take a meter reading
  2. Subtract the new meter reading from the previous read to work out the volume of gas used
  3. Multiply by the volume correction factor (1.02264)
  4. Multiply by calorific value (40.2)
  5. Divide by kWh conversion factor (3.6)
