Unit Definitions
What is a Joule (J)?
A Joule is the SI unit of energy, defined as the amount of energy transferred when one newton of force is applied over a distance of one meter.
History
The Joule was named after the English physicist James Prescott Joule, who studied the nature of heat and its relationship to mechanical work in the 19th century. His experiments laid the groundwork for the law of conservation of energy.
Current Use
Today, the Joule is widely used in various fields, including physics, engineering, and nutrition, to quantify energy.

A kilowatt-hour is a unit of energy equivalent to one kilowatt of power used for one hour.
History
The kilowatt-hour was established as a unit of energy in the late 19th century, coinciding with the rise of electric power generation. It became essential for measuring electricity consumption.
Current Use
Kilowatt-hours are commonly used in billing by electric utilities, helping consumers understand their energy usage and costs.
