What is a poundal (pdl)?

A poundal is a unit of force in the foot–pound–second (FPS) system, defined as the force that accelerates one pound-mass at one foot per second squared.

What does a petanewton (PT) measure?

The petanewton is an SI-derived force unit equal to 10^15 newtons, used to express extremely large forces such as those in planetary and stellar physics.

Why convert poundals to petanewtons?

Converting from poundals to petanewtons helps compare small-scale legacy forces to vast astronomical or geological forces, useful in education and scientific research.
