What is a microjoule used for?

A microjoule is used to quantify very small amounts of energy such as pulse energies in ultrafast lasers, energy stored in small capacitors, and mechanical work in micro-scale devices.

Why convert microjoules to Hartree energy?

Converting microjoules to Hartree energy helps relate practical energy measurements to atomic units commonly used in quantum chemistry and atomic physics calculations.

What should I be careful about when converting units?

You should be cautious of the large numerical factor involved in the conversion and the difference in energy scales to avoid precision and rounding errors.
