What is a petanewton used for?

A petanewton is used to express extremely large forces encountered in planetary and stellar physics as well as geophysical processes.

How does ton-force (long) relate to mass?

Ton-force (long) represents the force equal to the weight of one long ton supported under standard gravity, used traditionally in older British lifting equipment.

Why convert petanewtons to ton-force (long)?

Converting petanewtons to ton-force (long) helps interpret very large SI-based forces in terms of traditional imperial units common in legacy engineering and historical documents.
