How to Convert Million BTU to Joules

To convert a million BTU measurement to a joule measurement, multiply the energy by the conversion ratio. One million BTU is equal to 1,055,055,852.62 joules, so use this simple formula to convert:

joules = million BTU × 1,055,055,852.62

The energy in joules is equal to the million BTU multiplied by 1,055,055,852.62.

For example, here's how to convert 5 million BTU to joules using the formula above.
5 MMBTU = (5 × 1,055,055,852.62) = 5,275,279,263.1 J

Million BTU and joules are both units used to measure energy. Keep reading to learn more about each unit of measure.

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.


The joule is the energy equal to the force on an object of one newton at a distance of one meter. One joule is equal to the heat energy dissipated by the current of one ampere through one ohm of resistance for one second.

One joule is also equal to the energy needed to move an electric charge of one coulomb through a potential difference of one volt. In addition, one joule is also equal to the one watt-second.

The joule is the SI derived unit for energy in the metric system. Joules can be abbreviated as J, for example 1 joule can be written as 1 J.
