Gigawatt-Hour
A gigawatt-hour (GW·h) is a unit of energy equal to one billion watt-hours, representing the amount of energy produced or consumed over one hour at a power level of one gigawatt.
History/Origin
The gigawatt-hour emerged as a standard unit of energy measurement in the 20th century with the development of large-scale power generation and electrical engineering, facilitating the quantification of energy production and consumption in power plants and grids.
Current Use
Gigawatt-hours are used today to measure large-scale energy production, consumption, and capacity in power systems, renewable energy projects, and national energy statistics, aiding in energy management and planning.
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.
