About the units

Therm (thm)

The US therm is 105,480,400 J, about 100,000 BTU. US gas utilities bill by the therm.

Megajoule (MJ)

The megajoule (MJ) is a unit of energy in the International System of Units (SI). One megajoule equals 1,000,000 joules (J).

Frequently asked questions

How many megajoules are in one therm?

There are 105.4804 megajoules in one therm, and this value is exact by definition.

How do I convert therms to megajoules?

Multiply the number of therms by 105.4804. For example, 10 thm × 105.4804 = 1,054.804 MJ.

How many therms are in one megajoule?

One megajoule equals 0.00948043428 therms. That is the reverse factor, 1 ÷ 105.4804.

What is 10 therms in megajoules?

10 thm = 1,054.804 MJ.

Is this thm to MJ converter accurate?

Yes. Both units are defined exactly in terms of SI units, so the conversion factor is exact; results are shown to 12 significant figures by default and you can change precision in the converter. Calculations run in your browser using the same tested engine that generated this page.
