To convert a measurement in british thermal units to a measurement in megajoules, multiply the energy by the following conversion ratio: 0.001055 megajoules/british thermal unit.

Since one british thermal unit is equal to 0.001055 megajoules, you can use this simple formula to convert:

megajoules = british thermal units × 0.001055

The energy in megajoules is equal to the energy in british thermal units multiplied by 0.001055.

For example, here's how to convert 500 british thermal units to megajoules using the formula above.
megajoules = (500 BTU × 0.001055) = 0.527528 MJ

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

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 Megajoule?

One megajoule is equal to 1,000,000 joules, which is the energy equal to the force on an object of one newton at a distance of one meter.

The megajoule is a multiple of the joule, which is the SI derived unit for energy. In the metric system, "mega" is the prefix for millions, or 106. Megajoules can be abbreviated as MJ; for example, 1 megajoule can be written as 1 MJ.
