What does a nutritional Calorie represent?

A nutritional Calorie represents a kilocalorie, equal to 1,000 small calories or 4,184 joules of energy, commonly used to quantify energy from food and beverages.

In what fields is the kiloelectron-volt used?

The kiloelectron-volt is used in atomic, nuclear, and radiation physics to describe energies of particles and photons at the atomic scale, such as X-rays and electron binding energies.

Why convert Calories to kiloelectron-volts?

Converting Calories to kiloelectron-volts helps relate macroscopic dietary energy to microscopic energies used in physics, supporting interdisciplinary research and analytical comparisons.
