How to Convert Million BTU to Kilojoules

To convert a million BTU measurement to a kilojoule measurement, multiply the energy by the conversion ratio.

Since one million BTU is equal to 1,055,055.85262 kilojoules, you can use this simple formula to convert:

kilojoules = million BTU × 1,055,055.85262

The energy in kilojoules is equal to the million BTU multiplied by 1,055,055.85262.

For example, here's how to convert 5 million BTU to kilojoules using the formula above.
5 MMBTU = (5 × 1,055,055.85262) = 5,275,279.2631 kJ

Million BTU

One million BTU is a measure of heat energy equal to 1,000,000 BTU, which are equal to the amount of heat energy required to increase the temperature of one pound of water one degree Fahrenheit.

The million BTU is a US customary unit of energy. Million BTU can be abbreviated as MMBTU; for example, 1 million BTU can be written as 1 MMBTU.


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.
