Definition
Pound foot per square second 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. This unit is equivalent to one poundal.
History/Origin
Pound foot per square second 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 unit represents the fundamental relationship between mass, acceleration, and force.
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 (metric)
tf
Definition
Ton-force (metric) represents the gravitational force exerted on a metric ton (1,000 kg) under standard gravity conditions. It equals approximately 9,807 Newtons and is used for measuring very large forces in industrial and engineering applications.
History/Origin
Ton-force emerged as a practical unit for expressing large forces in industrial applications. It was particularly useful in heavy industry, mining, and construction where forces are measured in tons. The metric version became standardized with the adoption of metric systems worldwide.
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. Used in some European engineering standards and specifications for large-scale applications.
