How to read your meter

FortisBC uses both imperial and metric meters. Imperial meters measure gas use in hundreds of feet, and metric meters measure gas use in single cubic metres.
We also use two styles of meter registers: digital index registers and clock-style registers.

Digital index registers

Reading a digital index register is as easy as reading your car's odometer. We use digital index registers for both imperial (measuring hundreds of cubic feet) and metric (measuring single cubic metres) meters. Each digital meter is clearly marked to show imperial or metric measurement.

To find out the volume of gas you've used since your last statement, just subtract your last reading from your current reading, like this:

Current  

Last        

In the example above, your volume used over the period equals 238 cubic metres.

Clock-style registers

Clock-style meters generally measure gas in hundreds of cubic feet. Reading a clock-style register is not hard once you get the hang of it. If you have a clock-style meter, read the dials from zero to nine, either clockwise or counter clockwise as indicated on the dial.

  • If the dial hand is between the numbers, use the lower one (if between 9 and 0,
    read 9).
  • If the dial hand is exactly on a number, look at the dial to the immediate right. If its dial hand is not past zero, record the lower number for the dial in question.

Move the pointer on each dial above to see how a clock-style meter works.

You can also run the meter:

  • Click inside the box above and "Enter" or "Return" to start the meter.
  • Hit any key or click inside the box to stop the meter.

To find out the volume of gas you've used since your last statement, just subtract your last reading from your current reading, like this:

Volume of gas used  
Present reading 15,800
Less your previous reading
(you'll find this on your statement)
-7,400
Gas used (cubic feet) 8,400

How to calculate your gas bill

If you want to read your meter to see how your gas bill is calculated, remember that you are billed for the energy you use, not the volume of gas recorded by your meter. Meters measure the volume of gas used - and that information allows us to calculate how much energy is used in your home each month.

We use a conversion factor to translate volume of gas used into energy consumed (measured in gigajoules). The conversion factor (shown in the box on the right hand side of your FortisBC bill) takes into account your location's standard conditions of temperature and pressure, as well as the average energy content of the gas.

To check your gas bill against your meter reading:

  • subtract previous reading from present reading = the volume of gas used
  • multiply by the Conversion Factor (as noted on your gas bill) = the number of gigajoules you are being billed for.

What's a gigajoule?

A gigajoule - is the standard measurement for a unit of heat, equal to 948,213 Btu. You are billed for energy used as measured in gigajoules.
