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

Especially in colder months, a lot of homeowners want to know how to convert therms to MMBTU. This has to do with the use of natural gas for space and water heating (gas furnaces, water heaters). We will show you how to easily convert therms to MMBTU. To make things even easier, you will also get Therms To MMBTU Calculator (just insert therms, get MMBTU) and a chart where we have converted 0.1 to 1,000 therms into MMBTU.

The conversion will become immediately apparent if we just look at these two units:

  • Therm is a unit for heat content (usually for natural gas). 1 Therms is equal to 100,000 BTU. As we know, BTU or British Thermal unit is the amount of energy we need to heat 1 pound of water by 1 degree Fahrenheit. You will find therms on your gas bill, denoting the amount of used natural gas.
  • MMBTU stands for Metric Million British Thermal Unit. It is also a unit for heat content. 1 MMBTU is equal to 1,000,000 BTU (million BTU).
therms vs mmbtu for natural gas
The quantity of natural gas we use is usually expressed in therms (on the monthly gas bills).

As we can see, if 1 therm = 100,000 BTU and 1 MMBTU = 1,000,000 BTU, we can easily write this relationship in an equation like this:

MMBTU = Therms / 10

This just means that 1 MMBTU is equal to 10 therms (1 MMBTU = 10 therms). Quite easy conversion, right?

Quick Example: How many MMBTU is 100 therms? Let’s use the equation to convert this:

MMBTU (100 Therms) = 100 Therms / 10 = 10 MMBTU

100 therms is equal to 10 MMBTU. This conversion is very simple. Here is the Therms To MMBTU Calculator that makes this conversion automatically. Further on, we have also converted 0.1 therms to 1000 therms into MMBTU and gathered the results in a chart you can consult:

Alright, let’s figure out how many MMBTU is 32 therms. Just slide the slider to ’32’ and you get the result: 32 therms is equal to 3.2 MMBTU.

Here is the full conversion chart:

Therms: MMBTU
0.1 Therms 0.01 MMBTU
0.5 Therms 0.05 MMBTU
1 Therm 0.10 MMBTU
2 Therms 0.20 MMBTU
3 Therms 0.30 MMBTU
4 Therms 0.40 MMBTU
5 Therms 0.50 MMBTU
6 Therms 0.60 MMBTU
7 Therms 0.70 MMBTU
8 Therms 0.80 MMBTU
9 Therms 0.90 MMBTU
10 Therms 1.00 MMBTU
20 Therms 2.00 MMBTU
30 Therms 3.00 MMBTU
40 Therms 4.00 MMBTU
50 Therms 5.00 MMBTU
60 Therms 6.00 MMBTU
70 Therms 7.00 MMBTU
80 Therms 8.00 MMBTU
90 Therms 9.00 MMBTU
100 Therms 10 MMBTU
150 Therms 15 MMBTU
200 Therms 20 MMBTU
250 Therms 25 MMBTU
300 Therms 30 MMBTU
400 Therms 40 MMBTU
500 Therms 50 MMBTU
1000 Therms 100 MMBTU

As you can see, MMBTU is a 10-times bigger unit for natural gas heat content than a therm.

Example: How many MMBTU is 70 therms? You can easily consult this chart to get the result: 70 therms is equal to 7 MMBTU.

With the formula, calculator, and this chart, you will be able to (quite easily) convert therms to MMBTU. If you encounter any problems, you can use the comments below, give us some numbers, and we will help you out.
