What is a Therm?

A therm is a unit of measurement of energy (more specifically thermal energy). The therm is used to measure gas consumption:

  • 1 Therm = 100,000 British thermal units (BTU)

This is equal to 29.3 kWh of thermal energy.

1 therm of heat is obtained by burning 100 cubic feet (=1 CCF) of natural gas.

Since it is easier to measure a volume of gas (in CCF) than natural gas' thermal energy, your gas meter will count the amount of gas you consume each month in CCF and not in Therms. On your gas bill, you gas consumption will most usually be firstly expressed in CCF, and then converted to Therms. Also, since 1 Therm is equivalent to 1 CCF, the conversion is rather simple.
