What is a petanewton used for?

A petanewton is used to measure extremely large forces in planetary-scale physics, astrophysics, and geophysics such as gravitational attraction between large astronomical bodies.

What does pound foot/square second represent?

Pound foot per square second is a unit of force in the foot–pound–second system equal to the force needed to accelerate one pound mass at one foot per second squared.

Why convert petanewtons to pound foot/square second?

Converting allows translating large SI force values into legacy imperial units commonly found in older engineering documents and specific educational contexts.
