How to Convert Kilojoules to British Thermal Units

To convert a measurement in kilojoules to a measurement in british thermal units, multiply the energy by the following conversion ratio: 0.947817 british thermal units/kilojoule.

Since one kilojoule is equal to 0.947817 british thermal units, you can use this simple formula to convert:

british thermal units = kilojoules × 0.947817

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

For example, here's how to convert 5 kilojoules to british thermal units using the formula above.

british thermal units = (5 kJ × 0.947817) = 4.739086 BTU

How Many British Thermal Units Are in a Kilojoule?

What Is a Kilojoule?

One kilojoule is equal to 1,000 joules, which is 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 thousands, or 10³. Kilojoules can be abbreviated as kJ; for example, 1 kilojoule can be written as 1 kJ.

What Is a British Thermal Unit?

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.
