What is pound-force used for?

Pound-force represents the force produced by gravity on one pound mass and is commonly used to express weights, thrust in engines, and mechanical loads in US customary units.

Why convert pound-force to ton-force (metric)?

Conversion to metric ton-force facilitates expressing large force values in metric units, which is common in engineering fields such as crane load ratings and civil construction.

Is the ton-force (metric) an SI unit?

No, metric ton-force is a non-SI unit defined by the force of one metric tonne under standard gravity and may not be accepted in all scientific contexts.
