How to Convert Kilojoules to British Thermal Units

To convert a kilojoule measurement to a british thermal unit measurement, multiply the energy by the conversion ratio. One kilojoule is equal to 0.947817 british thermal units, so use this simple formula to convert:

british thermal units = kilojoules × 0.947817

The energy in british thermal units is equal to the kilojoules multiplied by 0.947817.

For example, here's how to convert 5 kilojoules to british thermal units using the formula above.
5 kJ = (5 × 0.947817) = 4.739086 BTU

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


One kilojoule is equal to 1,000 joules, which are the energy equal to the force on an object of one newton at a distance of one meter.

The kilojoule is a multiple of the joule, which is the SI derived unit for energy. In the metric system, "kilo" is the prefix for 103. Kilojoules can be abbreviated as kJ, for example 1 kilojoule can be written as 1 kJ.

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.
