What does this tool do?
A gas bill is usage multiplied by the unit rate, plus standing charges and taxes. Reading the meter yourself separates the energy you used from estimated billing and makes seasonal comparisons more reliable.
The Formula
Usage = current reading − previous reading; bill = usage × rate + fixed chargeFrequently Asked Questions
Why does my bill not match the meter?
Bills often include standing charges, taxes and levies, and some meters apply a conversion factor. Estimated readings can also differ from actual use; submit a reading to correct them.
What is the difference between a therm and a CCF?
One CCF is 100 cubic feet of gas and is roughly 1.037 therms. Both measure the same gas in different billing units.
