How to convert meter reading to kWh?

sho_me_da_money

Guys,

I was looking at my meter readings and couldn't work out how they converted a newly submitted reading to how many kWh were consumed? Anyone experts know what to do?

Here's an example of the last 6 readings:

20/01/2011 - 24826 - Customer Read - 6609.0
25/11/2010 - 24237 - Meter Reader - 4712.0
16/08/2010 - 23816 - Meter Reader - 1304.0
21/05/2010 - 23698 - Meter Reader - 5602.0
17/02/2010 - 23200 - Meter Reader - 7594.0
16/11/2009 - 22518 - Meter Reader - 2860.0

First Column = Date
Second Column = Meter Reading
Third Column = How it was submitted/read
Fourth Column = Consumption in kWh

Is there any way for me to work out an estimated consumption of the meter readings or is it impossible?

I was hoping to work out my average daily consumption and perhaps predict the one for the next bill.

OR do I need to invest in an OWL or similar device?

Is this for gas or electric?
If it's electric I understand a unit is a kwh (stand to be corrected)
If it is gas, input the readings on mysmartmeter and it will give the kwh used

This is Gas.

What is a mysmartmeter?

Hi sho me,
Normally the way they convert is shown on the bill,
However you appear to have a metric meter which measures Cubic metres and the formula is,
Units used x calorific value(39.4) x Volume correction (1.02264) all divided by 3.6.
I have used the figures from my bill, they can vary very slightly.

But the easy way for you to convert is to multiply the units used by 11.2, that gives an accurate enough figure.

What a hoot!( hoot owl get it!!)


From your latest readings.

24826 - 24237 = 589M3 of gas x 11.2 = 6596.8 Kwh.

This was over a period of approx 57 days, so your average daily consumption for the cold spell was 6596.8/57 = 115.7 Kwh

Assuming Gas @ £0.038per Kwh your daily average cost has been £4.40.

Phew thats a lot of gas unless my maths has gone kerrputt!

Sorry to be fly in the ointment but calorific value changes depending on the area of the UK you live in eg former Midlands Electric Board region have a calorific value of 39.2, yet former Yorkshire electric board region it is 40.2 calorific value, and even this does not hold true throughout those regions, I live in south yorkshire and would have fallen under YEB, yet my calorific value is 39.4 - check your current gas bill it will have your calorific value on there.

I live near Leicester so east midlands and my calorific value is 39.4 on my Scottish power bill.

It gets better - it also varies with time!
This is what makes sure you are charged for the amount of energy, not the volume of gas. If your gas is lower quality, you will need to use more of it to heat your home = low CV.

Stornoway = 93.0. That's some calorific value!!!! :eek:
