Microjoule
A microjoule (µJ) is a unit of energy equal to one millionth of a joule, used to measure small amounts of energy.
History/Origin
The microjoule was introduced as part of the metric system to facilitate the measurement of very small energy quantities, especially in scientific and engineering contexts, with the adoption of the International System of Units (SI).
Current Use
Microjoules are commonly used in fields such as electronics, physics, and biology to quantify small energy transfers, signals, or reactions, often in research and technical applications.
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.
