Petanewton
A petanewton (PT) is a unit of force equal to 10^15 newtons, used for measuring extremely large forces.
History/Origin
The petanewton was introduced as part of the SI prefixes to facilitate the expression of very large forces, although it is rarely used in practical applications due to the scale of forces involved.
Current Use
The petanewton is primarily used in scientific contexts involving large-scale forces, such as astrophysics and cosmology, but remains a theoretical unit with limited practical application.
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.
