Therms to Gigajoules Converter

Convert therms (100,000 Btu) (thm) to gigajoules (GJ), 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 = 0.105505585262 GJ

Show the working
  1. 1 thm = 0.105505585262 GJ
  2. 1 × 0.105505585262 = 0.105505585262 GJ

How to convert therms to gigajoules

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

GJ = thm × 0.105505585262
thm = GJ × 9.47817120313

Worked example:

1 thm = 0.105505585262 GJ
5 × 0.105505585262 = 0.52752792631 GJ
