What is Hartree energy used for?

It is the atomic unit of energy commonly used in atomic physics and quantum chemistry to report electronic energies and energy differences.

What does a megaton [Mton] represent?

A megaton measures energy equivalent to the explosion of one million metric tons of TNT and is used for very large explosive or impact energies.

Why convert Hartree energy to megaton?

Converting helps relate microscopic energy calculations to very large-scale energy events, such as nuclear explosions and asteroid impacts, providing a perspective on energy magnitude.
