Unit Definitions
What is a Watt-hour (Wh)?
The watt-hour (Wh) is a unit of energy representing the amount of energy consumed by a device using one watt of power for one hour.
History
The watt-hour has its origins in the work of James Watt in the late 18th century, who developed the steam engine and emphasized the measurement of energy. It became widely adopted with the rise of electrical appliances in the 20th century.
Current Use
Today, the watt-hour is commonly used in electrical engineering, utility billing, and appliance specifications to indicate energy consumption.

The joule (J) is the SI unit of energy, defined as the energy transferred when one newton of force is applied over a distance of one meter.
History
Named after the English physicist James Prescott Joule, the joule has been in use since the 19th century and is fundamental in the field of thermodynamics and energy calculations.
Current Use
The joule is widely used in scientific contexts, especially in physics and engineering, to measure energy, work, and heat.
