Gram-Force
Gram-force (gf) is a unit of force defined as the force exerted by one gram of mass in standard gravity, approximately equal to 0.00980665 newtons.
History/Origin
The gram-force originated in the late 19th and early 20th centuries as part of the centimeter-gram-second (CGS) system of units, used to express forces in terms of grams and centimeters. It was commonly used in physics and engineering before the adoption of the SI system.
Current Use
Gram-force is now largely obsolete and replaced by the SI unit newton (N) in scientific and technical contexts. However, it may still be used in some engineering fields, calibration, and for illustrative purposes in educational settings.
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.
