How to Convert Ton-Force (Long) to Attonewton
1 tonf (UK) = 9.96401642e+21 aN
Example: convert 15 tonf (UK) to aN:
15 tonf (UK) = 15 × 9.96401642e+21 aN = 1.494602463e+23 aN
Ton-Force (Long) to Attonewton Conversion Table
| ton-force (long) | attonewton |
|---|
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.
Attonewton
An attonewton (aN) is a unit of force equal to 10^-18 newtons.
History/Origin
The attonewton is part of the SI prefixes system, introduced to measure extremely small forces, with its usage becoming more relevant in nanotechnology and precision measurements.
Current Use
Attonewtons are used in scientific research involving microscopic forces, such as in atomic and molecular physics, and in nanotechnology applications where very small forces are measured.
