Understanding the Units

What is a Kilowatt Hour?

A kilowatt-hour equals exactly 3,600,000 joules — the energy delivered by 1 kW of power over one hour. It is the standard unit on electric utility bills.

Common contexts: electricity billing, home energy, EV battery capacity.

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.
