What is a petanewton?

A petanewton is an SI-derived unit of force equal to 10^15 newtons, used to express very large forces in planetary and stellar physics.

A poundal is a unit of force in the foot-pound-second system, defined as the force causing a 1 foot per second squared acceleration on one avoirdupois pound.

Why convert petanewtons to poundals?

Converting petanewtons to poundals facilitates comparison and integration of large-scale force data between modern SI-based studies and classical mechanics or legacy engineering contexts.
