Calculating volume from reading on gas meter calibrated in ft cubed

[hebl]

My gas supplier tells me that each unit recorded on my gas meter represents 100 cub ft,
so the first step in the calculation process is to multiply the amount of units used by 100.
Surely this cannot be right ?

Why do you want to do this?

But yes, if you want to find the volume of gas you've used from the meter and 1 unit = 100ft³ then you multiply by 100 for each unit.

Not sure what you mean by "first step" either, if you want the volume on ft³ then *100 is the only step.

Not Quite.

Gas meters measure volume of gas used either in cubic metres or cubic feet. Gas, however, is priced in Kilowatt Hours (the same as electricity). To convert cubic metres to Kwh you have to perform the following calculation (which I have cribbed from one of the suppliers’ websites). You need to use the “Imperial meters” calculation. The figure of 2.83 converts hundreds of cubic feet into cubic metres as 2.83 cubic metres is equivalent to 100 cubic feet.

All the figures we use to convert your gas usage into kWh can be found underneath your gas meter readings on your bill.

Here's how we do it:

1. For imperial meters: Take the volume used, shown with 'hcf' on the front of your bill and multiply this figure by 2.83 to convert to cubic metres (m³). Then follow step 2 onwards.

For metric meters: Take the volume used, shown with 'm³' on the front of your bill.

2. Multiply this figure by the conversion factor of 1.02264, then by the calorific value shown on your bill underneath your meter readings.

3. Finally divide this figure by 3.6 to show your usage in kWh.

A rough and ready way to do this is to multiply the “hundreds of cubic feet” figure from your imperial meter by 31.5 to get Kwh (the units your gas is charged in). The equivalent calculation for metric gas meters is to multiply the cubic metres by 11.1.

That'll teach me to blindly answer questions :) but I did assume that the statement "My gas supplier tells me that each unit recorded on my gas meter represents 100 cub ft," meant just what it says.

Actually your answer addressed the question more properly, CF. I just assumed that hebi was trying to relate the cubic feet used into Kwh to understand the costs involved.
