How to Convert Therms to Joules

To convert a measurement in therms to a measurement in joules, multiply the energy by the following conversion ratio: 105,505,585.262 joules/therm.

Since one therm is equal to 105,505,585.262 joules, you can use this simple formula to convert:

joules = therms × 105,505,585.262

The energy in joules is equal to the energy in therms multiplied by 105,505,585.262.

For example, here's how to convert 5 therms to joules using the formula above.
joules = (5 therms × 105,505,585.262) = 527,527,926.31 J

How Many Joules Are in a Therm?

There are 105,505,585.262 joules in a therm, which is why we use this value in the formula above.

1 therms = 105,505,585.262 J

What Is a Therm?

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.

What Is a Joule?

The joule is the energy equal to the force on an object of one newton at a distance of one meter.[1] 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.
