Btu (th) or thermochemical British thermal unit is an energy unit defined as the heat needed to raise one pound of water by one degree Fahrenheit based on thermochemical calorie values.

Why convert Btu (th) to microjoules?

Converting to microjoules allows expressing large thermal energies in a finer SI unit suitable for scientific precision and micro-scale energy applications.

Where is the microjoule unit commonly used?

Microjoules measure very small amounts of energy, such as pulse energy in lasers, small capacitor energy, and mechanical work in microsystems.
