What does one gigajoule represent?

One gigajoule is an SI-derived unit of energy equal to one billion joules, often used to measure large thermal or mechanical energy amounts.

Why use gigaton as an energy unit?

Gigaton expresses extremely large energy releases by comparing them to the energy of one billion metric tons of TNT, useful in nuclear and planetary sciences.

Is the gigaton unit precise for scientific calculations?

No, it mainly serves for order-of-magnitude estimates and lacks precise accuracy for detailed energy measurements.
