* We use a Geolocation to identify your state. However, it's not always accurate. Therefore, you may need to adjust your local prices to correct values (see table at the bottom).

Additionally, prices provided for your state are AVERAGE for your whole state, and may differ greatly from one part of the state to another. We inlcude local prices for your convenience. However, for accuracy purposes, it is ideal for end user to correct these prices to what local suppliers actually charge!

To get your accurate rate, refer to you Electric, and Gas (or Oil/Propane) bill.

US Energy Costs table by State:

Here is the price table of Heating Fuels such as Natural Gas, Fuel Oil, Propane and Electicity, for each state, including Washington DC, AL and HI, as well as US average.

Natural Gas prices are in THERMS, which is an equivalent of about 100,000 BTUs, but can easily be converted to 100/1000 Cu. Ft. See how to do it below the price table.

Notes:

** NOTE: If your gas company charges you in units other than therms here are local CT and US average costs for natural gas in other common delevery units:

COMMON Gas measurement units:
CCF = 100 Cubic Ft.
MCF = 1000 Cubic Ft.

Price per CCF (in CT): $2.4
Price per MCF (in CT): $24.02

Price per CCF (US Average): $2.4
Price per MCF (US Average): $24.02

One therm is almost the same as 1 CCF. However, "almost the same" is the key here!

The heat content of Therm is 99976 BTUs, while 1 CCF has 103675.112 BTUs, and 1 MCF has 1036751.12 BTUs.

Why are THERMS, CCF & MCF important?

Our heating energy cost calculator uses THERMS to estimate cost of heating with natural gas, but since every gas company uses their own units of calculating your cost of gas, it is important that you provide correct unit cost, to get accurate estimate.

Basically, there are approximately 3.7% more BTUs in 1 CCF vs 1 Therm, which means that you will need 3.7% fewer CCFs to produce same heat as if you calculated in therms.

Bottom line:

  • If your gas company is charging you is CCF you should divide your Cost/CCF by 1.037, and adjust the GAS Price devide your in the calculator.
  • If your gas company is charging you is MCF you should divide your Cost/MCF by 10.37, and adjust the GAS Price devide your in the calculator.
  • If you currently do not use Natural Gas, then you don’t need to do anything.
