Therm To CCF Formula
The following equation is used to convert therms to CCF when the CCF value is unknown.
CCF = TH / CF
- Where CCF is the hundred cubic feet of natural gas
- TH represents therms (a unit of heat energy)
- CF is the conversion factor (therms per CCF)
To calculate the CCF, divide the therms by the conversion factor.

What is a Therm to CCF?
Definition:
The therm to CCF conversion is used in the natural gas industry to translate an energy measurement (therms) into a volume measurement (hundred cubic feet, or CCF). The conversion factor indicates how many therms are contained in one CCF and is essential for accurate billing and energy assessment.
How to Calculate Therm to CCF?
Example Problem:
The following example outlines the steps and information needed to calculate the CCF using the therm to CCF formula.
First, determine the therms value. In this example, assume there are 150 therms.
Next, determine the conversion factor. In this example, the conversion factor is 1.03 therms per CCF.
Finally, calculate the CCF using the formula above:
CCF = TH / CF
CCF = 150 / 1.03
CCF = 145.6311 CCF
FAQ
What factors can affect the therm to CCF conversion?
Several factors such as gas composition, temperature, and pressure can influence the conversion factor used in therm to CCF conversions. It is best to verify the conversion factor with your local utility provider for the most accurate measurement.
Can this calculator compute any missing value?
Yes, simply leave the field for the value you wish to calculate blank while providing the other two values. The calculator will then compute the missing value using the appropriate formula.
Why is the conversion factor important?
The conversion factor is essential as it defines the number of therms contained in one CCF, ensuring that energy measurements are accurately translated into volume for billing and analysis.
