Gram-Force Meter
A gram-force meter (gf·m) is a unit of torque or moment of force, representing the force of one gram-force applied at a distance of one meter from the pivot point.
History/Origin
The gram-force meter originated from the use of the gram-force as a unit of force in the centimeter-gram-second (CGS) system, primarily used in scientific and engineering contexts before the adoption of SI units.
Current Use
Today, the gram-force meter is rarely used; it is mainly of historical interest or in specific niche applications where CGS units are still referenced, but most torque measurements are expressed in SI units such as newton-meters.
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.
