Therms to kJ Converter

Convert therms (thm) to kilojoules (kJ). 1 therm = 105,480.4 kilojoules (exact)

1 therm (US) = 105,480.4 kilojoules

How to convert therms to kilojoules

FormulakJ = thm × 105,480.4

Multiply the value in therms by 105,480.4. To go the other way, multiply by 0.00000948043428 (or divide by 105,480.4).

A therm is larger than a kilojoule: one therm contains 105,480.4 kilojoules.

About the units

Therm (thm)

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

Kilojoule (kJ)

One thousand joules. Food labels in Australia and the EU list energy in kJ alongside kcal. One kilojoule equals 1,000 joules (J).

Frequently asked questions

How many kilojoules are in one therm?

There are 105,480.4 kilojoules in one therm, and this value is exact by definition.

How do I convert therms to kilojoules?

Multiply the number of therms by 105,480.4. For example, 10 thm × 105,480.4 = 1,054,804 kJ.

How many therms are in one kilojoule?

One kilojoule equals 0.00000948043428 therms. That is the reverse factor, 1 ÷ 105,480.4.

What is 10 therms in kilojoules?

10 thm = 1,054,804 kJ.

Is this thm to kJ 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.
