Convert poundal to ton-force (long)
Please provide values below to convert poundal [pdl] to ton-force (long) [tonf (UK)], or Convert ton-force (long) to poundal.
1 pdl = 1.3875423742e-05 tonf (UK). To convert poundal to ton-force (long), multiply the value by 1.3875423742e-05; to go the other way, divide by it (1 tonf (UK) = 72069.8710607 pdl). Both units measure force and appear in everyday as well as technical calculations, so switching between them quickly is often useful.

Poundal
The poundal (pdl) is a unit of force in the foot-pound-second (FPS) system, defined as the force required to accelerate a one-pound mass at a rate of one foot per second squared.
History/Origin
The poundal was introduced in the 19th century as part of the FPS system of units, primarily used in engineering and physics in the United States before the widespread adoption of the SI system.
Current Use
Today, the poundal is largely obsolete and rarely used, having been replaced by the SI unit newton; however, it may still be referenced in historical contexts or specialized engineering fields.
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.
