MMBTU To Therms Calculator + Chart (1 MMBTU = 10 Therms)

MMBTU and therms are both units for heat content (usually for natural gas). It’s incredibly easy to calculate therms from given MMBTU. We will show you exactly how to do it. Further on, you will also find MMBTU To Therms Calculator you can freely use, as well as a chart with 0.1 to 10,000 MMBTU converted into therms.

Let’s get acquainted with these two natural gas heat content units we are converting:

  • MMBTU or Metric Million British Thermal Unit is a measure of heat content equal to 1,000,000 BTU.
  • Therm is also a unit of heat content, but 1 therm is equal to 100,000 BTU.
therms vs mmbtu for natural gas
The quantity of natural gas we use is usually expressed in therms (on the monthly gas bill).

As we can see, MMBTU is a 10 times bigger unit than therms. Based on this, we can write this very easy MMBTU to therms formula:

Therms = 10 × MMBTU

From this equation, it is quite apparent that 1 MMBTU = 10 therms.

Quick Example: Let’s say we want to convert 50 MMBTU to therms. How many therms is that? Let’s use the equation above like this:

Therms (50 MMBTU) = 10 × 50 = 500 Therms

50 MMBTU is equal to 500 therms.

You can do this equation by hand, or you can use our MMBTU To Therms Calculator (further on, we have also converted 0.1 to 10,000 MMBTU into therms, and summarized the results in a neat conversion chart):
