Gas - m3 to KWH calculation and very high usage
Does anyone know if the measured quantity and the cost calculation is identical across all suppliers (obviously subject to calorific value changes) ? I need to calculate the cost of the gas we're using before i get a bill.
I'm asking because we moved into a new house (new build EPC
and comparing my energy consumption since November against my previous property shows a very similar electricity usage but a VASTLY higher gas usage (about 1.2 m3/day last December vs 4.3 m3/day for Nov/Dec). So assuming that the meter is measuring the same thing using the same gas we're spending around £5 a day on gas !!
Calc i'm using is...
volume x imperial rate x calorific value x volume correction / 3.6 = kWh
15 m3 x 2.83 x 39 x 1.02264 / 3.6 = 470.28 which at 2.807p is £13.20 for 3 days use....

You're using the procedure for a reading in (hundreds of) cubic feet.AndyHamp said:Calc i'm using is...volume x imperial rate x calorific value x volume correction / 3.6 = kWh

Your old house might have an Imperial meter; you new one a metric meter. That introduces a factor of 3.Never pay on an estimated bill. Always read and understand your bill0

Cubic metres multiplied by 11 is good enough conversion to kwh for fag packet estimates.
15 x 11 is 165 x 2.807p
£4.63 plus standing charge and VAT.
To check imperial £4.63 x 2.83 £13.10, not far off £13.20!!1 -
If it's 15m3 x 11 x 2.807p = £4.63 , which is £1.54/day then i'm not so frightened considering it's damned cold...daveyjp said:Cubic metres multiplied by 11 is good enough conversion to kwh for fag packet estimates.

But your comment about checking imperial values has confused me.0 -
It's like worrying that you'll be busted for driving at 80kph in a 50mph zone.

For what it's worth the meter is this ...
which is metric 0 -
Which model of L&G meter is it? There's an interesting Rogue meters thread!0

Hi,so it's a metric meter (m3), you don't need the (x 2.83) in your calculation,15 m3 x 2.83 x 39 x 1.02264 / 3.6 = 470.28 which at 2.807p is £13.20 for 3 days use....remove the ( x 2.83) you get £4.66.
