Natural gas is commonly measured by the cubic foot, which is a measurement of volume and billed by the therm, which is a measurement of energy. One therm is the energy content equal to 100,000 Btu (British Thermal Units), which is the amount of energy used to raise the temperature of one pound of water by one degree Fahrenheit – the energy required to produce heat.
The majority of gas meters on the JEA system has a multi-dial display reading window that shows four or five small dials with arrows and numbers and are a little more challenging to read. Each dial is numbered 0-9 (0 at the top), has a pointer hand and has a directional arrow above it. The pointer hand in each dial moves from the smaller number to the larger one.
To read the meter:
Meters are typically read around the same time each month, with the date read reflected on your most current bill statement. Usage is determined by subtracting the previous month’s meter read from the current month’s meter read. Billing cycles can range anywhere from 28-32 days depending on holidays and weekends and are indicated on your monthly bill.
