I need metric meter calculation help please!

Hi

Just watched 'Watchdog' about imperial/metric meters and have checked my gas bill. We have a metric meter and our calculation is:

149 units x factor 100 x correction factor 1.02264 = 15237.33
15237.33 x conversion factor 0.0283 = 431.21
431.21 cu mtrs x calorific value 39.1/3.6 = 4683.41 kWh

From what I have read on the Watchdog website, this looks wrong. Does anyone know why they are multiplying by 100 at the start and why they are using a conversion factor?

I think it should be 149 x correction factor 1.02264 x calorific value 39.1/3.6 = 1654.944 kWh

But I could be completely wrong! I'd be grateful if anyone could shed any light...

Every metric gas unit is approx 11.2kWh(calorific value varies)

149 x 11.2 = 1669kWh.

Don't forget that an Imperial gas unit is 100 cubic feet.

You are definately being charged for an imperial meter so if you have a metric one you are being over charged. Which supplier are you with as it is a very strange method of calculating your usage, why multiply by 100 then later on by 0.0283, surely simply multiplying by 2.83 is easier.

We're with Atlantic - it's definitely a metric meter. I'll give them a call. Glad I saw Watchdog!
