Convert ton-force (long) to femtonewton
Please provide values below to convert ton-force (long) [tonf (UK)] to femtonewton [fN], or Convert femtonewton to ton-force (long).
1 tonf (UK) = 9.9640e+18 fN. To convert ton-force (long) to femtonewton, multiply the value by 9.9640e+18; to go the other way, divide by it (1 fN = 1.0036e-19 tonf (UK)). Both units measure force and appear in everyday as well as technical calculations, so switching between them quickly is often useful.
Quick Reference
- 1 tonf (UK) = 9.9640e+18 fN

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.
Femtonewton
A femtonewton (fN) is a unit of force equal to 10^-15 newtons.
History/Origin
The femtonewton is part of the metric system's SI prefixes, introduced to measure extremely small forces, particularly in scientific and engineering contexts involving micro- or nano-scale phenomena.
Current Use
Femtonewtons are used in fields such as nanotechnology, molecular physics, and precision measurements where forces at the femtonewton scale are relevant.
