# What are Ccf, Mcf, Btu, and therms? How do I convert natural gas prices in dollars per Ccf or Mcf to dollars per Btu or therm?

**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 2014 the average heat content of natural gas for the residential, commercial, and industrial sectors was about 1,028 Btu per cf; one Ccf = 102,800 Btu or 1.028 therms; one Mcf = 1.028 MMBtu or 10.28 therms.

You can convert prices from one basis to another:

$ per Ccf divided by 1.028 = $ per therm

$ per therm multiplied by 1.028 = $ per Ccf

$ per Mcf divided by 1.028 = $ per MMBtu

$ per Mcf divided by 10.28 = $ per therm

$ per MMBtu multiplied by 1.028 = $ per Mcf

$ per therm multiplied by 10.28 = $ per Mcf
