Below is a step by step process for calculating gas kWh:
Calculation for imperial gas meters
Task Sample
1) Number of units used 100
2) Convert from imperial to metric – multiply number of units used by 2.83 (fixed) 283
3) Multiply by volume correction factor (1.022640) 289.407
4) Multiply by calorific value (39.3) 11373.699
5) Divide by kWh conversion factor (3.6- Fixed) 3159.361
6) Multiply by read factor 3159.361
Note that the correction factor changes
Note that the calorific value changes
Read factor to be determined by supplier / meter details
