Natural Gas CCF To Therms Calculator + Chart (1 CCF = 1.037 Therms)

The volume of natural gas is sometimes expressed in CCF (Centum Cubic Feet). The heat content of that natural gas is expressed in therms. In many cases, we need to convert CCF to therms. To help you with this conversion, we have created a simple CCF To Therms Calculator (insert CCF, get therms) alongside the CCF To Therms Conversion Chart (0.1 CCF to 1000 CCF converted into therms).

Here is a short summary of the units we are converting:

  • CCF stands for Centum Cubic Feet. This is a volumetric unit for natural gas equal to 100 cubic feet of natural gas (100 CF). Centrum = 100 in latin.
  • Therm is a unit of heat content equal to 100,000 BTU (hundred thousand BTU). BTU or British Thermal Unit is the basic unit for heat content; 1 BTU is the energy needed to increase the temperature of 1 pound of water by 1 degree Fahrenheit.

We will find “CUBIC FEET” on a gas meter. CCF is equal to 100 cubic feet of natural gas.

The relationship between the CCF of natural gas and therms is very close to 1:1. Here is the only conversion data point we need to convert CCF to therms:

“100 cubic feet (CCF) of natural gas equals 103,700 BTU, or 1.037 therms.” (Source: US Energy Information Administration)

That means that:

  • 1 CCF is equal to 1.037 therms.
  • 1 therm is equal to 0.96432 CCF.

As you can see, the relationship is very close to 1:1 (only 3.7% difference). In approximation, 1 CCF is equal to 1 therm. Here is the exact CCF to therms formula that the calculator below uses to make this conversion:

Therms = CCF × 1.037

Quick example: How many therms of heat content are in 50 CCF of natural gas? Simple. Just insert the ’50 CCF’ into the equation above like this:

Therms (50 CCF) = 50 CCF × 1.037 =51.85 Therms

As you can see, 50 CCF of natural gas contains 51.85 therms of heat content.

To make this calculation even simple, you can use this CCF to therms calculator. You can find the CCF to therms chart where we converted 0.1 CCF and up to 1000 CCF into therms, and summarized them in the neat table (found below this the calculator):

CCF To Therms Calculator

Here you just insert CCF. The calculator will automatically convert CCF input into therms output (you can play around with numbers to see how the therms output changes):


Here is how this calculator works:

Let’s say you want to convert 80 CCF to therms. Just slide the slider to ’80’ and you get the result: 80 CCF is equal to 82.96 therms.

We have converted anywhere between 0.1 CCF and 1000 CFM to therms. Here is the full conversion chart:
