Poundal
pdl
Definition
The poundal is a unit of force in the foot-pound-second (FPS) system of units. It is defined as the force required to accelerate a mass of one pound at a rate of one foot per second squared. The poundal is equal to approximately 0.138 Newtons.
History/Origin
The poundal was introduced as part of the FPS (foot-pound-second) system of units in the 19th century. It was widely used in physics and engineering before the adoption of the MKS (meter-kilogram-second) system. The name comes from the combination of "pound" and "acceleration".
Current Use
Still used in some areas of physics and engineering, particularly in the United States. Common in some engineering applications where the FPS system is still used. Used in some scientific instruments and laboratory equipment that were designed using the FPS system.

Ton-force (long)
tonf (UK)
Definition
Ton-force (long) represents the gravitational force exerted on a long ton (2,240 pounds) under standard gravity conditions. It equals approximately 9,964 Newtons and is used for measuring very large forces in industrial and engineering applications, particularly in the United Kingdom.
History/Origin
Ton-force (long) emerged as a practical unit for expressing large forces in industrial applications, particularly in the United Kingdom. It was particularly useful in heavy industry, mining, and construction where forces are measured in tons. The long ton version became standardized in the UK.
Current Use
Used in heavy industry for measuring large forces, such as in mining equipment, construction machinery, and industrial presses. Common in shipbuilding and offshore engineering in the United Kingdom. Used in some UK engineering standards and specifications for large-scale applications.
