What is ton-force (long) used for?

Ton-force (long) represents the force from a long ton mass under standard gravity and is used in older British imperial measurements, especially for cranes, presses, and naval load ratings.

How is pound-force defined?

Pound-force is the force generated by standard gravity on a one avoirdupois pound mass and is used widely in US customary and Imperial systems for expressing force.

Why convert from ton-force (long) to pound-force?

Converting from ton-force (long) to pound-force helps translate legacy British imperial forces into more granular and commonly used Imperial or US customary units, facilitating engineering and historical analyses.
