Therms to Kilojoules Converter

Convert therms (100,000 Btu) (thm) to kilojoules (kJ), with the formula, a conversion table and exact factors.

Change the values and press Calculate to work out your own figures.

Enter an amount of energy, choose its unit and the unit you want. The answer is exact until it is shown, and the same value appears in every other unit.

A number, fraction (3/8), mixed number (1 1/2), scientific notation (2.5e6) or a simple sum such as 2*3.
The unit you want the answer in. Swap exchanges the two units.

1 thm = 105,505.585262 kJ

Show the working
  1. 1 thm = 105505.585262 kJ
  2. 1 × 105505.585262 = 105505.585262 kJ

How to convert therms to kilojoules

1 thm = 105,505.585262 kJ, so multiply by 105,505.585262 to go from therms (100,000 Btu) to kilojoules. Going the other way, 1 kJ = 9.47817120313 × 10⁻⁶ thm.

kJ = thm × 105,505.585262
thm = kJ × 9.47817120313

Worked example:

1 thm = 105505.585262 kJ
5 × 105505.585262 = 527527.92631 kJ
