Frequently Asked Questions
What are Ccf, Mcf, Btu, and therms? How do I convert prices in Ccf and Mcf to Btus and therms?
C — equals one hundred(100).
Ccf — equals the volume of 100 cubic feet (cf) of natural gas.
M — equals one thousand (1,000).
MM — equals one million (1,000,000).
Mcf — equals the volume of 1,000 cubic feet (cf) of natural gas.
MMBtu — equals 1,000,000 British thermal units (Btu) (One Btu is the heat required to raise the temperature of one pound of water by one degree Fahrenheit.).
Therm — One therm equals 100,000 Btu, or 0.10 MMBtu.
In 2011, the average heat content of natural gas for the residential, commercial, and industrial sectors was about 1,023 Btu per cf; one Ccf = 102,300 Btu or 1.023 therms; one Mcf = 1.023 MMBtu or 10.23 therms.
You can convert prices from one basis to another as follows:
$ per Ccf divided by 1.023 = $ per therm
$ per therm multiplied by 1.023 = $ per Ccf
$ per Mcf divided by 1.023 = $ per MMBtu
$ per Mcf divided by 10.23 = $ per therm
$ per MMBtu multiplied by 1.023 = $ per Mcf
$ per therm multiplied by 10.23 = $ per Mcf
