# 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 2013, the average heat content of natural gas for the residential, commercial, and industrial sectors was about 1,025 Btu per cf; one Ccf = 102,500 Btu or 1.025 therms; one Mcf = 1.025 MMBtu or 10.25 therms.

You can convert prices from one basis to another:

$ per Ccf divided by 1.025 = $ per therm

$ per therm multiplied by 1.025 = $ per Ccf

$ per Mcf divided by 1.025 = $ per MMBtu

$ per Mcf divided by 10.25 = $ per therm

$ per MMBtu multiplied by 1.025 = $ per Mcf

$ per therm multiplied by 10.25 = $ per Mcf
