Kilopound-Force
A kilopound-force (kipf) is a unit of force equal to 1,000 pounds-force, primarily used in engineering and construction to measure large forces.
History/Origin
The kilopound-force originated in the United States as a practical unit for structural engineering, especially in the context of large-scale construction projects, and has been used since the mid-20th century.
Current Use
Today, the kilopound-force is mainly used in civil and structural engineering within the US to specify forces in design and analysis, although it is less common internationally due to the adoption of SI units.
Ton-Force (Long)
A unit of force equal to the force exerted by one long ton (2,240 pounds) under standard gravity, approximately 20,000 pounds-force.
History/Origin
The ton-force (long) originated from the use of the long ton in the UK, primarily for engineering and maritime purposes, before the adoption of SI units. It was used to measure force in contexts where imperial units were standard.
Current Use
The ton-force (long) is largely obsolete in modern scientific and engineering contexts, replaced by the newton. It may still be used in some historical or niche applications within the UK or in legacy systems.
