What does 1 erg represent in energy units?

1 erg is a CGS unit of energy equal to 1×10⁻⁷ joule and measures mechanical, thermal, or electromagnetic energy.

What is a gigaton (Gton) in terms of energy?

A gigaton (Gton) represents the energy equivalent of one billion metric tons of TNT, roughly 4.184 × 10¹⁸ joules.

Why convert erg to gigaton for energy measurements?

This conversion helps translate very small-scale CGS energy values into extraordinarily large energy scales useful in fields like nuclear science and planetary science.
