To convert a measurement in british thermal units to a measurement in kilojoules, multiply the energy by the following conversion ratio: 1.055056 kilojoules/british thermal unit.

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 energy in british thermal units multiplied by 1.055056.

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

How Many Kilojoules Are in a British Thermal Unit?

There are 1.055056 kilojoules in a british thermal unit, which is why we use this value in the formula above.

1 BTU = 1.055056 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.

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.
