How to Convert British Thermal Units to Gigajoules

To convert a british thermal unit measurement to a gigajoule measurement, multiply the energy by the conversion ratio. One british thermal unit is equal to 1.0551E-6 gigajoules, so use this simple formula to convert:

gigajoules = british thermal units × 1.0551E-6

The energy in gigajoules is equal to the british thermal units multiplied by 1.0551E-6.

For example, here's how to convert 500,000 british thermal units to gigajoules using the formula above.
500,000 BTU = (500,000 × 1.0551E-6) = 0.527528 GJ

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

British Thermal Units

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.

Gigajoules

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

The gigajoule is a multiple of the joule, which is the SI derived unit for energy. In the metric system, "giga" is the prefix for 109. Gigajoules can be abbreviated as GJ, for example 1 gigajoule can be written as 1 GJ.
