How to Convert Joules to British Thermal Units

conversion scale showing joules and equivalent british thermal units energy values

To convert a joule measurement to a british thermal unit measurement, multiply the energy by the conversion ratio. One joule is equal to 0.000948 british thermal units, so use this simple formula to convert:

british thermal units = joules × 0.000948

The energy in british thermal units is equal to the joules multiplied by 0.000948.

For example, here's how to convert 5,000 joules to british thermal units using the formula above.
5,000 J = (5,000 × 0.000948) = 4.739086 BTU

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

Joules

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.

British Thermal Units

British thermal units are a measure of heat energy. Specifically, one british thermal unit is equal to the amount of heat energy required to increase the temperature of one pound of water one degree Fahrenheit. They are often used as a way to rate the energy heat producing appliances such furnaces, and to price heating fuels such as natural gas.

The british thermal unit is a US customary unit of energy. British thermal units can be abbreviated as BTU, for example 1 british thermal unit can be written as 1 BTU.
