How to Convert British Thermal Units to Kilojoules

To convert a british thermal unit measurement to a kilojoule measurement, multiply the energy by the conversion ratio.

Since one british thermal unit is equal to 1.055056 kilojoules, you can use this simple formula to convert:

kilojoules = british thermal units × 1.055056

The energy in kilojoules is equal to the british thermal units multiplied by 1.055056.

For example, here's how to convert 5 british thermal units to kilojoules using the formula above.
5 BTU = (5 × 1.055056) = 5.275279 kJ

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

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.

Kilojoules

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.
