Conversion Definitions
lb: A unit of weight or force in the imperial system, equal to about 0.453592 kilograms, used mainly in the United States for measuring weight, mass, or force. It represents the force exerted by gravity on a pound-mass.
Newtons: The SI unit of force, defined as the force needed to accelerate a one-kilogram mass by one meter per second squared, approximately equal to 1 kg·m/s². It measures force, weight, or tension in metric systems.
