What does one gigaton represent in energy terms?

One gigaton corresponds to the energy equivalent of one billion metric tons of TNT, approximately 4.184 × 10^18 joules.

Why convert gigaton to megajoule?

The conversion translates extremely large energy values into a standard scientific unit, facilitating detailed energy calculations and comparisons.

Is the gigaton unit precise for energy measurement?

No, the gigaton is an order-of-magnitude, non-SI unit primarily for very large energy estimates rather than precise analysis.
