Kilowatt Hour to Electron Volt Converter

A kilowatt-hour (kWh) is a unit of energy equal to the energy consumed by a device with a power rating of one kilowatt operating for one hour. It equals 3.6 megajoules and is the standard unit for measuring electrical energy consumption.

The kilowatt-hour was developed with the commercialization of electricity in the late 19th century. It provided a practical way for electric utilities to measure and bill for electrical energy consumption, becoming the standard unit for electrical energy trading worldwide.

Kilowatt-hours are universally used for measuring and billing electrical energy consumption in homes, businesses, and industries. They're found on every electricity bill, used in energy efficiency ratings for appliances, and are standard in renewable energy system specifications and grid energy trading.

An electron volt (eV) is a unit of energy equal to approximately 1.602 × 10⁻¹⁹ joules. It represents the kinetic energy gained by an electron when accelerated through an electric potential difference of one volt.

The electron volt was introduced in the early 20th century with the development of atomic and nuclear physics. It provided a convenient energy scale for atomic and subatomic processes, where joules would result in extremely small numbers with many decimal places.

Electron volts are extensively used in atomic physics, nuclear physics, particle physics, and materials science. They're standard for measuring atomic binding energies, photon energies, particle accelerator energies, and electronic band gaps in semiconductors.
