Ounce-Force to Ton-Force (Long) Conversion Table
| ounce-force | ton-force (long) |

Ounce-Force
Ounce-force (ozf) is a unit of force equal to the force exerted by one ounce under standard gravity, approximately 0.278 Newtons.
History/Origin
The ounce-force originated from the imperial and US customary systems, used historically for measuring small forces, especially in engineering and physics contexts before the widespread adoption of the Newton as the SI unit.
Current Use
Ounce-force is rarely used today, primarily in legacy systems or specific industries such as aerospace and mechanical engineering where imperial units are still in use, but it has largely been replaced by the Newton in scientific and international contexts.
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.
