How many therms do we get from 1 MCF of natural gas? We will need this information to adequately convert any number of MCF to therms. To help you out, we have derived the MCF to formula, as well as created a simple-to-use MCF To Therms Conversion Calculator and a chart with MCF (1 to 10,000 MCF) converted to therms.
Here are the units we’ll be converting:
- MCF is a unit of volume (usually the volume of natural gas). MCF is equal to 1000 cubic feet; that M is a roman numeral for ‘1000’, hence MCF stands for Thousand Cubic Feet.
- Therm is a unit of heat content. 1 Therm is equal to 100,000 BTU. BTU or British Thermal Unit is one of the most basic units for heat content we use in HVAC.

In order to figure out how many therms of heat content we have in different volume (expressed in MCF) of natural gas, we only need to know this relationship:
1 MCF is equal to 10.73 therms (for natural gas).
This comes from the energy density of natural gas, as measured by the US Energy Information Administration (EIA).
That means that we can use this simple formula for MCF to therms conversion:
Therms = MCF × 10.37
Example: Let’s say we want to know what is the heat content (in therms) of 50 MCF of natural gas. We just plug these 50 MCF into the equation like this:
Therms (50 MCF) = 50 MCF × 10.37 = 518.50 Therms
This is just one example. To calculate MCF from therms from any volume of natural gas, you can use the following MCF To Therms Calculator and you can consult the MCT To Therms Conversion Chart that follows the calculator:
Note: If you have any issues with this conversion, you can use the comment section below, give us some figures, and we will help you out. If you want to convert therms to MCF, you can use a similar Therms To MCF calculator here.
MCF To Therms Conversion Calculator
Just input MCT, and the calculator will automatically convert that to therms (you can play around with the slider to see how therms change);
Here is a simple example: Let’s say you want to know how many therms is 250 MCF of natural gas. Just slide the slider to ‘250’ and you get the result: 250 CFM is equal to 2592.50 therms.
Here is a full chart converting a wide range of MCF (from 0.1 MCF to 10000 MCF) to therms:

1000 MCF Of Natural Gas | 10,370 Therms |
10,000 MCF Of Natural Gas | 103,700 Therms |
To get the therms of heat content in X number of MCF of natural gas, you simply read it off this chart. For example, how many MCF is 10 therms? Check the chart above and you can see that 10 MCF is equal to 103.70 therms.
With these two tools (calculator + chart), you will be able to convert the MCF of gas to therms quite easily. If you need any help, use the comment section below, tell us what you want to calculate, and we will help you out.
I live in a Mobile trailer home ,2 bedrooms kitchen living room and bathroom ,you think a 100 gallon tank could heat up my hpme
Hi Diana, well, sure it will, but for how long. If you have cold winters, you will probably have to refuel the 100 gallon propane tank a few times during the winter.
