Understanding the Units

What is an Electronvolt?

An electronvolt equals approximately 1.602 × 10⁻¹⁹ joules — the kinetic energy gained by a single electron accelerated through a one-volt potential difference.

Common contexts: particle physics, atomic spectroscopy, semiconductor band gaps.

What is a Kilocalorie?

A kilocalorie (kcal) equals 1,000 small calories, or 4,184 joules. In nutrition, the food "Calorie" (capital C) refers to the kilocalorie.

Common contexts: nutrition (US), metabolism, food labeling.
