CONVERTING GAS UNITS TO KILOWATT-HOURS (KWH)

Solution

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) 100’s cu ft x 2.83.   10’s cu ft x 0.283.   cu ft x 0.0283                                                                                                       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
