How to Convert Joules to Therms

To convert a joule measurement to a therm measurement, multiply the energy by the conversion ratio. One joule is equal to 9.4782E-9 therms, so use this simple formula to convert:

therms = joules × 9.4782E-9

The energy in therms is equal to the joules multiplied by 9.4782E-9.

For example, here's how to convert 5 joules to therms using the formula above.
5 J = (5 × 9.4782E-9) = 4.7391E-8 therms

Joules and therms are both units used to measure energy. Keep reading to learn more about each unit of measure.


The joule is the energy equal to the force on an object of one newton at a distance of one meter. One joule is equal to the heat energy dissipated by the current of one ampere through one ohm of resistance for one second.

One joule is also equal to the energy needed to move an electric charge of one coulomb through a potential difference of one volt. In addition, one joule is also equal to the one watt-second.

The joule is the SI derived unit for energy in the metric system. Joules can be abbreviated as J, for example 1 joule can be written as 1 J.


One therm is a measure of heat energy equal to 100,000 BTU, which are equal to the amount of heat energy required to increase the temperature of one pound of water one degree Fahrenheit. Therms are often used by natural gas companies to measure the heat equivalent of gas used.

The therm is a US customary unit of energy.
