webntweb Posted September 22, 2021 Share Posted September 22, 2021 Trying to sort out how much gas I use at home but some of the terms used are confusing to say the least. Switching sites ask for your gas usage in kwh but my present energy company gives my usage in mega joules. When looking to see how to convert mega joules to kwh I have also come across gas measured in cubic feet and cubic metres. I would be grateful if somebody could enlighten me on how I can make the conversion from mj to kwh. Quote Link to comment Share on other sites More sharing options...
annv Posted September 22, 2021 Share Posted September 22, 2021 Hi Roy My gas meter reads in cubic meters but charges in Kwh Joules is the energy in each m3 on one of my bills is 305 units m3 = 3387 kWh hope this helps you could google the formula. so roughly times ten.

annv Posted September 22, 2021 Share Posted September 22, 2021 Hi Roy divide calcific by 36 this will give you rough kWh. John 1 Quote Link to comment Share on other sites More sharing options...
