What is a newton (N)?

A newton is the SI derived unit of force, defined as the force needed to accelerate a mass of one kilogram by one meter per second squared.

How is pound-force (lbf) defined?

Pound-force is a unit of force in the U.S. customary and Imperial systems, defined as the force exerted by standard gravity on a one avoirdupois pound mass.

Why convert newtons to pound-force?

Conversion is useful to express forces in US customary units, especially for applications in aerospace, engineering, and testing that use Imperial units.
