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
A therm 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 by the American Gas Association to standardize natural gas billing and measurement; it became widely adopted in North America for energy calculations.
Current Use
Today, the therm is still used in the natural gas industry for billing and energy measurement, although other units like gigajoules and cubic meters are also common globally.
