Joule

The joule (J) is the SI unit of energy, work, and heat, defined as the work done when a force of one newton acts over a distance of one meter.

History/Origin

The joule was named after James Prescott Joule in 1889 to honor his work in energy and thermodynamics. It was adopted as the SI unit of energy in 1948.

Current Use

The joule is widely used in physics, engineering, and everyday contexts to quantify energy, work, and heat in various applications, including electricity, mechanics, and thermodynamics.


Megawatt-Hour

A megawatt-hour (MW·h) is a unit of energy equal to one megawatt of power sustained for one hour.

History/Origin

The megawatt-hour has been used since the development of large-scale electrical power systems to quantify energy production and consumption, especially in power generation and grid management, becoming standard in the 20th century.

Current Use

It is commonly used today to measure electricity generation, consumption, and capacity in power plants, utilities, and energy markets worldwide.
