The number of therms used is determined by multiplying the CCF consumption by an energy factor. The energy factor is determined from the monthly average BTU content of the natural gas as it is delivered through the transmission pipeline. 1 Therm (natural gas) = 1 CCF x Energy Factor (BTU conversion factor). Think of therms in comparison to grades of gasoline.
