How to Change the CCF to Therms
- 1). Look at your gas bill. It will typically show the present reading and the previous reading from your meter in units of CCF. The difference between the two is the volume of gas you have consumed. Make a note of this number.
- 2). One CCF of gas is approximately equal to 1 therm of energy. For example, if your gas bill shows you have consumed 36 CCF, the energy value of this gas is approximately 36 therms. This approximation is widely used in the gas industry to convert CCF to therms.
- 3). The exact value of the conversion factor is set by the gas company, and is usually slightly more than 1.0. Note that Southern California Gas uses a value of 1.017 as the conversion factor. Berkshire Gas uses a conversion value of 1.024. The U.S. Energy Information Administration gives the conversion factor as 1.029. If your gas company is Berkshire Gas, multiply 36 CCF by 1.024 to get 36.864 therms.
- 4). Look again at your gas bill and find the exact conversion factor used by the gas company. Multiply this number by the volume of gas in CCF to obtain a precise value for the energy content of the gas in therms.
