Conundrum 2

[said]

Here's one for you, a simple maths problem.
My gas meter is one which registers readings in 100 cubic feet, in order to work out the consumption costs I have to convert to metric and then adjust the volume correction which allows me to adjust the calorific value and then eventually convert from joules.
To convert 100 cu/f
x metric conversion
x volume correction
x calorific value
\3.6 convert from joules
This will give me my usage in kWh which I can then multiply by 2.6450 p\kWh
For example 100 x 2.83 x 1.02264 x 39.3 \ 3.6 = 3159.4 kWh

What would my consumption in kWh be if my meter reading is 225 units

225 x 2.83 x 1.02264 x 39.3/ 3.6 = 7106.89 (7107KWh) ?

or 7?

or 7?

No, because you have converted cubic feet to cubic metres by multiplying by 2.83.

100 cu. feet = 2.83 cubic metres.

225 x 2.83 x 1.02264 x 39.3/ 3.6 = 7106.89 (7107KWh) ?

Close, but no cigar!

The answer is a general one for the UK. There are differences in the answer depending on what figures are used within certain regions and for which energy company you are with.

Maybe so, but you've made an error in your stated calculation.

225 x 2.83 x 1.02264 x 39.3/ 3.6 = 7,108.56

In case you're getting confused I've put in a traditional division sign.

There are differences in charges but all the information you require is in my original post, although your post regarding gas charges is to some extent relevant to the correct solution.

Incidentally the figures used are those applied to GB Energy, Fixed 12 Crystal.

100 x 2.83 x 1.02264 x 39.3 ÷ 3.6 = 3159.4 kWh

What would my consumption in kWh be if my meter reading is 225 units

With the figures given it is likely, but I used exact fractions in my calculations.

On those figures 3159.4 x 2.25 = 7108.65 KWh.

On those figures 3159.4 x 2.25 = 7108.65 KWh.

I'm glad to see that you and I arrived at the same figure, (you'll have to take my word for that).

I referred to GB Energy as I was a customer of theirs for almost 12 months.

Customarily, I search the web to find a better deal and in doing so I endeavoured to finalise my existing bill.

I read the meter and made the calculations.

To check that I had followed the formula correctly I decided to check a previous bill and was amazed that my figures didn't tally with the previous bill.

I checked another bill the same result, I double checked, I treble checked, each time the results showed a difference to my bills.

Had they been lower than mine, I'd have put it down to a lesser education, however they were all higher charges than the figures I came up with.

When I contacted GB Energy, the customer services agent suggested that my figures were incorrect and theirs were right.
We went over the figures together he eventually agreed that my figures were correct and he made an adjustment to my final bill.
Their calculation 225 = 7156.1 kWh

Not an enormous amount just over 100 kWh @2.645p for the incorrect bills but better in my pocket than theirs. Referring to your 'Gas Bill thread', I think you'll agree there's something going on.

I wonder how many people check their bills, especially using the conversion data supplied by the suppliers which in my case was in favour of the utility company?
I believe GB Energy had somewhere in the region of 160,000.

Good for you! The majority of people would not have bothered to check as they consider the mathematics involved is far too complicated and they trust the supply companies. If you take the amount that you were being overcharged and multiply that by a few hundred thousand - then you can see where the supply companies get an easy profit from. Anyway well done - you are not a victim!
