How to Convert Kilojoule to Therm
- 1 kJ = 0.00000948043428 thm
- 1 thm = 105480.4 kJ
- Example: convert 15 kJ to thm: 15 kJ = 15 × 0.00000948043428 thm = 0.0001422065142 thm
Reference conditions. thm: US therm, 100 000 BTU (59 °F), 105.4804 MJ as given by NIST SP 811. The EC therm is 105.506 MJ.
Formula
thm = kJ × 0.000009480434279733
or thm = kJ ÷ 105480.4
Derivation from SI units:
- 1 kJ = 10³ J
- 1 thm (US) = 1.054804 × 10⁸ J (NIST SP 811)
- 1 kJ = 1000 J ÷ 105480400 J per thm = 0.000009480434279733 thm
Both units are defined exactly, so the factor is exact. Kilojoule definition: kilojoule; Therm definition: therm.
Worked examples
- A reading of 100 kJ converts to 0.000948043428 thm.
100 kJ × 0.00000948043428 = 0.000948043428 thm - A value of 1000 kJ is 0.00948043428 thm.
1000 kJ × 0.00000948043428 = 0.00948043428 thm

Frequently asked questions
How many therms are in 1 kilojoule?
1 kJ = 0.00000948043428 thm.
How do I convert kilojoules to therms?
Multiply the value in kJ by 0.00000948043428, or divide it by 105480.4. For example, 15 kJ × 0.00000948043428 = 0.0001422065142 thm.
Is the kJ to thm conversion exact?
Yes. Both units are defined exactly, so the ratio is exact; its decimal form does not terminate and is shown here to 10 significant figures (more with the precision selector).
