Gas conversion factors

What are the conversion factors used to convert imperial gas readings to kilowatt hours

@Gasfitter1

This may be of some help?

Thank you @Allanr we also put it on your bills @Gasfitter1 at the bottom of the page with a breakdown of your gas usage, there’s a lovely little box with a couple of lines of multiplication and division that takes you from 100s of ft³ to m³ to kWh
