Calculation

swiftandsure

Any maths experts out there who could tell me how to convert 341 Scottish Power gas units to Kwh please. I've looked at their instructions but unfortunately not having a maths degree it is all gobbledegook to me. Why they give you electricity in Kwh but gas in units is beyond my comprehension unless it is designed to baffle us?

I did try to contact them but surprise, there was a fault on their website email and I got fed up of typing the same thing over and over.

Thanks

You don't need to the bill will do it for you.

If you want an estimation then use the website http://www.ukpower.co.uk/tools/smart_meter_calculator/

It will be close to the amount on the bill varying depending on the calorific value of the gas.

Hi Swiftandsure,

God I think Im a master at this, or atleast I should be after being in dispute with Scottish Power for 7 years now.
Right you need to have a look on your bills & find out what your volume correction is. Mine was around 39.2, but I find that this amount goes up & down all the time. I dont know where they get this from but thats what you need first, the 2nd figure you need is the calorific value, this should be near to where you found the volume correction as far as I know this is always the same 1.022640p

Confused yet, yep so was I.
Lets say for example your volume correctrion is at 39.2
You have used 341 Units.
Calculation as follows:- 341 x 39.2 x 1.022640 divided by 3.6 =
3797 (always round up)

So now you need to determine what tarriff your on. If your on 2 seperate rates for your gas, you will be charged a higher rate (Primary) for the day & lower rate (secondary) for the night. I think you get the seperate rates if you are not paying standing charges. The primary rates, replace the standing charges.
How to determine what is Primary & what is Secondary - Lets say your billing is seperated into quarterley. For every 90 days, the first 1044 units are charged at your primary rate. For every unit used after that, it is then charged at your secondary rate. Once the 90 days comes to an end, the primary rate starts again. Does this make sense.
Now if your on standing charges, Im not to sure how it works, I think you are just charged one standard rate for all usage day & night & then you pay a standing charge of so much pence per day.

I do hope this has helped. Good Luck

The first thing you need to check is are the units cubic feet (ft3) or cubic metres (m3) get this wrong and the result will be well off.

Because electricity meters measure actual units of energy, (1 unit = 1kWh). Gas meters only measure volume, either cu m or 100's cu ft. Volume to energy is not a constant, hence the calorific value adjustment to get to kWh, as well as the volume to energy (kWh) conversion.
As above, you need to check if your meter is metric or imperial, then use this site to do the conversion.

Cheers all. Think I get it now.
