What does one kilocalorie (IT) represent?

One kilocalorie (IT) equals 1,000 international-table calories, with each calorie defined as 4.1868 joules.

When is using the gigaton unit appropriate?

Gigaton units are used to express the energy of extremely large events like thermonuclear explosions or asteroid impacts for order-of-magnitude comparisons.

Why must the international-table calorie standard be used?

Using the international-table calorie ensures consistency in energy values since calorie definitions vary and affect conversions.
