Kilowatt-hours (kWh)

Definition

A kilowatt-hour (kWh) is a unit of energy equal to 1,000 watt-hours or 3,600,000 joules. It represents the energy consumed by a 1,000-watt appliance running for one hour.

History

The kilowatt-hour became the standard billing unit for electricity with the widespread electrification of homes and businesses in the early 20th century. Power utilities worldwide adopted it for metering.

Current use

Kilowatt-hours are the universal unit for residential and commercial electricity billing. They are also used to measure electric vehicle battery capacity, solar panel output, and grid-level energy storage.

Watt-hours (Wh)

Definition

A watt-hour (Wh) is a unit of energy equal to the work done by one watt of power sustained for one hour. It equals 3,600 joules.

History

The watt-hour emerged with the development of electrical power systems in the late 19th century. It provided a practical way to measure and bill for electrical energy consumption.

Current use

Watt-hours are used for small battery capacities (e.g., phone batteries, portable electronics) and as a base unit for kilowatt-hours used in household electricity metering.
