Understanding the Units

What is a Watt Second?

A watt-second is identical to one joule.

Common contexts: photography (flash energy), capacitor ratings.

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.
