How to convert gas units to kWh

First, you need to determine whether you have an imperial meter or a metric meter. For imperial meters, your reading will be in hundreds of cubic feet (100ft cubed). Metric meter readings are recorded in cubic meters (m cubed).

I have a metric gas meter

To convert metric meter readings to kWh, all you need to do is: 

• Take a meter reading, then subtract the previous meter reading from the new meter reading to work out the volume of gas used
• Multiply by volume correction factor (1.02264).
• Multiply by calorific value (40.0).
• Divide by kWh conversion factor (3.6).

I have an imperial meter

Calculate your reading as explained in the section above, then:

• Take a meter reading, then subtract the previous meter reading from the new meter reading to work out the volume of gas used. 
• Convert from imperial to metric by multiplying the units by 2.83.
• Multiply by volume correction factor (1.02264).
• Multiply by calorific value (40.0).
• Divide by kWh conversion factor (3.6).

If your imperial meter measures in cubic feet rather than hundreds of cubic feet, you’ll need to use 0.0283 for step 2 rather than 2.83. If it uses thousands of cubic feet, you’ll need to use 28.3 instead. Your meter will usually say ‘x100’ or ‘x1000’ to indicate the higher units of measurement.
