Gigajoules to Therms Converter

Convert gigajoules (GJ) to therms (100,000 Btu) (thm), 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. 1 GJ = 9.47817120313 thm
  2. 1 × 9.47817120313 = 9.47817120313 thm

How to convert gigajoules to therms

1 GJ = 9.47817120313 thm, so multiply by 9.47817120313 to go from gigajoules to therms (100,000 Btu). Going the other way, 1 thm = 0.105505585262 GJ.

thm = GJ × 9.47817120313
GJ = thm × 0.105505585262

Worked example:

1 GJ = 9.47817120313 thm
5 × 9.47817120313 = 47.3908560157 thm
