Millijoule
A millijoule (mJ) is a unit of energy equal to one thousandth of a joule, where 1 joule equals 1 newton meter or 1 kg·m²/s².
History/Origin
The millijoule is derived from the SI base unit joule, with the prefix 'milli' indicating a factor of 10⁻³. It has been used in scientific and engineering contexts to measure small amounts of energy, especially in fields like electronics and biomechanics.
Current Use
The millijoule is commonly used today to quantify small energy quantities in electronics, biomedical applications, and energy measurements where precision at a small scale is required.
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.
