Kilogram-Force Square Second/meter
Kilogram-force square second per meter (kgf·s²/m) is a derived unit used to measure a specific combination of force, time, and length, often in specialized engineering contexts.
History/Origin
The unit originates from the kilogram-force, a gravitational force unit based on the kilogram mass, combined with time and length units for specific applications. It has been used historically in mechanical and engineering calculations before the widespread adoption of SI units.
Current Use
Currently, kgf·s²/m is rarely used in modern engineering, having been largely replaced by SI units. It may still appear in legacy systems or specialized fields requiring non-standard units.
Grain
A grain is a unit of mass traditionally used to measure small quantities, primarily in the context of precious metals, pharmaceuticals, and firearms.
History/Origin
The grain dates back to ancient times and was originally based on the weight of a single seed of a cereal grain, such as barley. It has been used since the Middle Ages and was standardized in the apothecaries' system.
Current Use
Today, the grain is mainly used in the measurement of bullets, gunpowder, and precious metals, and is recognized as a unit of mass in the apothecaries' system, although it has largely been replaced by grams in most contexts.
