How to Convert BTUs to Microjoules
To convert btus to microjoules, multiply the energy by the following conversion ratio: 1,055,055,852.62 microjoules/british thermal unit.
Since one british thermal unit is equal to 1,055,055,852.62 microjoules, you can use this simple formula to convert:
The energy in microjoules is equal to the energy in btus multiplied by 1,055,055,852.62.
For example, here's how to convert 5 btus to microjoules using the formula above.
How Many Microjoules Are in a British Thermal Unit?
There are 1,055,055,852.62 microjoules in a british thermal unit, which is why we use this value in the formula above.

What Is a British Thermal Unit?
A british thermal unit is a unit of energy equal to 1,055.0558526 joules (J), the base unit for energy. Thermal energy unit equal to 1,055.056 Joules. [1]
The british thermal unit is classified as a US customary and imperial unit of energy. BTUs can be abbreviated as BTU; for example, 1 british thermal unit can be written as 1 BTU.
When working with btus (BTU) in formulas or technical specifications, always verify whether your target system uses SI metric, US customary, or British imperial standards.
In practice, btus (BTU) are widely used across large-scale industrial, bulk, and macro-level energy specifications within US customary and imperial workflows, engineering documentation, and technical data sheets.
What Is a Microjoule?
A microjoule is a unit of energy equal to 1/1,000,000 of a joule (0.000001 J). One-millionth of a Joule. [2]
The microjoule is classified as a metric and SI-compatible unit of energy. Microjoules can be abbreviated as µJ; for example, 1 microjoule can be written as 1 µJ.
In the metric system, "micro" is the standard SI prefix for millionths, or 10⁻⁶. This makes the microjoule (µJ) a convenient decimal multiple of the joule (J).
In practice, microjoules (µJ) are widely used across fine-tolerance laboratory, analytical, and micro-scale energy measurements within SI metric workflows, engineering documentation, and technical data sheets.
When converting energy between btus (BTU) and microjoules (µJ), keep full floating-point precision (1 BTU = 1,055,055,852.62 µJ; 1 µJ = 9.478171e-10 BTU) during intermediate calculations and round only the final microjoule figure to match your instrument tolerance.
