History

Pound-force (lbf)

The pound-force (lbf) is in the imperial system. It is the force gravity exerts on one pound of mass. Today, it is standardized to 4.44822 newtons. Pound-force has long been used in engineering, aviation, and the U.S. military. Despite the shift to metric, the pound-force (lbf) is still important in places that use imperial units. It is used in aerospace, engine performance, and mechanical testing. Its use demonstrates the enduring impact of imperial units.

Kilonewton (kN)

The kilonewton, symbol kN, equals 1,000 newtons. Engineers and construction professionals use it as a convenient unit for expressing large forces. They often measure the force exerted by vehicles, bridges, and aircraft components in kilonewtons. By using multiples of the newton, they maintain consistency with SI standards while reducing large numbers for practical readability. Civil engineers, aerospace professionals, and structural designers rely on the unit, where accurate force measurement is crucial for ensuring safety and optimal performance.
