Piconewton
A piconewton (pN) is a unit of force equal to one trillionth (10^-12) of a newton.
History/Origin
The piconewton was introduced as part of the SI prefixes to measure very small forces, especially in fields like biophysics and nanotechnology, where forces at the molecular or atomic scale are relevant.
Current Use
The piconewton is commonly used in scientific research to quantify tiny forces, such as those exerted by molecular motors, DNA stretching experiments, and nanoscale measurements.
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.
