## How to Convert British Thermal Units to Joules

To convert a measurement in british thermal units to a measurement in joules, multiply the energy by the following conversion ratio: 1,055.055853 joules/british thermal unit.

Since one british thermal unit is equal to 1,055.055853 joules, you can use this simple formula to convert:

joules = british thermal units × 1,055.055853

The energy in joules is equal to the energy in british thermal units multiplied by 1,055.055853.

For example, here's how to convert 5 british thermal units to joules using the formula above.
joules = (5 BTU × 1,055.055853) = 5,275.279263 J

### How Many Joules Are in a British Thermal Unit?

There are 1,055.055853 joules in a british thermal unit, which is why we use this value in the formula above.

1 BTU = 1,055.055853 J

## 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 Joule?

The joule is the energy equal to the force on an object of one newton at a distance of one meter.[1] 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.
