What does one kilocalorie (th) represent?

One kilocalorie (th) is a unit of energy exactly equal to 4,184 joules, commonly used to express energy content in food and some thermal applications.

Why use gigaton to express energy?

Gigaton is used as an order-of-magnitude unit for extremely large energy releases, such as nuclear explosions or planetary impact events.

Is the gigaton unit suitable for precise energy calculations?

No, gigaton is an approximate, non-SI unit suited for rough magnitude comparisons rather than precise energy computations.
