Kilowatt Hour to Erg 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 erg is a unit of energy in the centimeter-gram-second (CGS) system, equal to 10⁻⁷ joules. It represents the work done by a force of one dyne acting through a distance of one centimeter.

The erg was developed as part of the CGS unit system in the late 19th century. It was widely used in physics and engineering before the adoption of SI units, particularly in mechanics, thermodynamics, and electromagnetic calculations where CGS units were preferred.

Ergs are rarely used in modern applications, appearing mainly in historical scientific literature and some specialized physics contexts. They've been largely replaced by joules in all practical applications, though they may still appear in some older scientific references and specialized calculations.
