What's the equation to convert gas meter readings into kWh?

Hi @Florin1976 is this the Gas section of your bill? If so then the readings get converted to kWh like it says below on your bill.

We convert your metered gas units to kWh using the following formula: Metered volume × metric conversion factor × daily 1 calorific value × 1.02264 (volume correction) ÷ 3.6 = 2 kilowatt hours (kWh) used. 1 We convert the gas use into kWh according to your meter type – 2.83 (imperial) or 1 (metric).

I’m not sure if my father’s unit to Kwh conversion is right. His bills are really massive. When I looked at our bills and compared the conversions between his and mine they are totally different. i.e. 30 units of his are converted to 927.92Kwh, whereas mine are 36 units converted to 403.28Kwh. How can they be so different?? Should I challenge it?

Those figures are consistent with his meter measuring the gas volume in cubic feet, while yours measures cubic metres. It will say on the meter which it is - either  ft³, cu.ft or m³. Readings are then taken in 100s of cubic feet or whole cubic metres. See here: Gas meter readings and bill calculation - GOV.UK 

That would make sense. Although, my father passed away and we are clearing his house. So we have no hot water on and radiators are on for one hour a day. The bill is still £100 before standing change and vat which we can’t fathom. I’ll check his meter. Thanks.

Hiya,

I’m having issues getting to grips with OVO’s gas information which isn’t making sense to me. Electric seems to be fine and displaying the correct information for the readings, but gas...

This does not seem right to me from the opening reading to the closing (21625 - 21582 = 43) Which by my understanding is 43kwh energy used? Where exactly is OVO getting the 491.529 kwh of usage from?

Am I not understanding this or is there an issue with OVO?

As Jeffus says @Woojee there are calculations to be made on the meter readings for gas as it says on your bill. So it’s not just taking one reading from the other. 

Hi @Woojee can we mark this as complete now? 

I still have an old manual, non smart gas and electric meter. I barely use any gas, and my bills are very low (except they more than double with the standing charge which I’m not happy about). What I want to know is how and why OVO seem to be charging me 10 times the kWh usage?

For instance if as last month I started with a reading of 08621 at the beginning of the month and at the end of the month it was 08628, then surely that is 7kWh used and not the 77kWh they are charging me?

This very confusing how are they charging me 10 times the usage, it’s extremely baffling and I can’t work it out. Can anyone explain to me how this is actually supposed to work? The electricity amount is correct from what I can see, but this gas billing is not correct is it (or is it?). Thanks.

Hi @tval , your readings are in cubic meters which then get converted to kWh. 
OVO note the detail on your bill

It works out as you’ve seen

OK, thanks. I suffer from M.E. and it seems like a rather confusing way to do things, and I hate maths anyway and haven’t done any of these formula things since school, so it doesn’t mean a lot to me anyway, or most people come to that. All I’m concerned about is that I’m paying the correct amount.
