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.
Therm (Us)
The therm (US) is a unit of energy used primarily to measure natural gas consumption, equivalent to 100,000 British thermal units (BTUs).
History/Origin
The therm was introduced in the early 20th century as a practical unit for billing natural gas, standardizing energy measurement in the United States. It has been widely adopted in the energy industry for commercial and residential gas usage.
Current Use
Today, the therm (US) is still used in the natural gas industry for billing and energy calculations, although it has been largely supplemented by the gigajoule and other SI units in scientific contexts.
