Kilojoule
A kilojoule (kJ) is a unit of energy equal to 1,000 joules, used to quantify energy transfer or work done.
History/Origin
The kilojoule was introduced as part of the International System of Units (SI) to provide a convenient scale for measuring energy, especially in fields like nutrition and physics, replacing the joule for larger quantities.
Current Use
The kilojoule is widely used in nutrition to express food energy content, in physics and engineering to measure energy transfer, and in various scientific and industrial applications within the 'Energy' converter category.
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.
