What is a millijoule?

A millijoule (mJ) is an SI derived unit of energy equal to one thousandth of a joule, commonly used for measuring small amounts of energy like those in low-power lasers or microelectronic events.

What does one megaton represent in energy terms?

One megaton (Mton) represents the energy released by one million metric tons of TNT, a very large amount typically used to express nuclear explosions or massive impact energies.

Why convert millijoules to megatons if the values are so different?

Converting millijoules to megatons helps users understand the vast difference in energy scales and enables comparisons between extremely small energies and huge explosive events.
