How To Read Your Gas Meter

How Gas Meters Work

To measure the amount of gas you use, a gas meter is continually filling and emptying compartments inside the unit, which in turn moves the dials on the face of the meter (“the index”).  Your bill is calculated by comparing last month’s reading on file to the new reading.  The difference between those numbers indicates how much natural gas you used during that time period.

Reading the Gas Meter

Please see the illustration below as a guide.  Although the dials on your meter don’t look exactly like what is pictured, the same instructions apply regardless of meter manufacturer.

Start with the dial on the far left, and read to the right.  If a hand falls between two numbers, select the smaller number.  The only exception is when the hand falls between 9 and 0.  In that instance, use 9.


In the illustration below, dial 1 reads “0,” dial 2 reads “2,” dial 3 reads “9,” and dial 4 reads “1.” The correct reading for this dial is 0191.
