How do i convert to KW?

judip

i am looking to change gas and elec supplier, i rang EDF to ask for my yearly useage, they gave me meter readings and said i would have to convert it myself, i've done the gas but my elec bill doesn't tell me how to convert my yearly 4239 units to KWh. does anyone know how to do it?

you don't have to convert the 4239 is your annual kWh usage. You only have to convert gas you can either do that equation the long way or alternatively you could just multiply units by 31.3 to get a very accurate figure if you don't have the patience

many thanks

Hi,

I've been given my Gas consuption in Units, how do I change these into Kwh?

For gas that post might worry a lot of people!

The 31.3* Multiplication factor only applies to the older Imperial meters(unit measure is cubic feet) 1unit = 100 cu ft.

The majority of meters are now Metric and the measurement is in cubic metres. 1 unit = 1 cu mtr. The approx conversion ratio is 1 unit = 11.5kWh.*

There has been an ongoing program for some years to change all Imperial meters and fit Metric meters.

* The 31.3 and 11.5* figure can vary slightly as the calorific value of the gas supplied will vary; but they are close enough for an approximate estimate.

Money Miser - you need to check what type of meter you have. It will say M3(M cubed) or cu ft on it somewhere.

Thanks Cardew i was just in the process of amending this

Converting Units to Kilowatt Hours

Electricity consumption is usually already stated in kilowatt-hours on previous bills, so the electricity kWh's figure is ready to use.

Gas units need to be multiplied by 31.3 to convert from the units used according to the meter or bill, to kilowatt-hours. Then the gas kWh's are ready to use. This is a rough estimate and the exact conversion details are below. (Or, for rough figures, multiply by 100, then divide by 3).

(To convert gas units to kilowatt hours: gas units used x imperial to metric conversion factor (2.83) x volume conversion factor (1.022640) x calorific value (39.7) divided by kilowatt hour conversion factor (3.6) = kilowatt hours used.)( This is the same as: gas units used x 31.3 = kilowatt hours used).

If you have a metric meter, you do not need to use the imperial to metric conversion factor (2.83). In this case, the rough estimate is to multiply the metric units by 11 instead of 31.3.

Note that exact precision is not necessary because the objective is to use an amount which is close to what you used last year, and which will be the basis for what you estimate to use for the next 12 months.

Re-read post#2, or your bill, it should tell you how to.;)

Depends whether you meter is in cubic feet or metres.

Multiplying cu ft by 31.3 is ok, as wills 34 said.

Whoops must try to type quicker :rolleyes2

There is a converter here (does both cubic feet and metres)
