What does one nutritional Calorie represent?

One nutritional Calorie (capital C) is a kilocalorie (kcal), equivalent to 1000 small calories and equals 4,184 joules of energy.

Why use gigaton to express energy?

Gigaton expresses extremely large energy releases, such as nuclear explosions or asteroid impacts, providing order-of-magnitude comparisons.

Can I use this conversion for precise engineering calculations?

No, the gigaton unit is not suitable for exact calculations and is mainly used for conceptual comparisons due to its large scale.
