What is a megajoule used to measure?

A megajoule (MJ) measures large amounts of energy such as work, heat, chemical energy, and electrical energy.

Why use gigaton as an energy unit?

Gigaton (Gton) expresses extremely large energy amounts like nuclear explosions or asteroid impacts, making big values easier to understand.

Can I use this conversion for everyday energy calculations?

No, gigaton is not suitable for everyday or small-scale energy measurements; it is meant for very large energy events.
