Convert pound force to newton
Pound-force
The pound-force (lbf) is a unit of force in the imperial and US customary measurement systems. It is defined as the force exerted on a mass of one avoirdupois pound by the standard acceleration due to gravity, 9.80665 m/sĀ², giving it a value of approximately 4.44822 newtons. The pound-force is widely used in the United States in engineering, aviation, and everyday contexts to express forces and weights. It should be distinguished from the pound-mass (lbm), which measures mass rather than force.
Newton
The newton (symbol: N) is the SI unit of force, named after Sir Isaac Newton. One newton is the force needed to accelerate a mass of one kilogram at one metre per second squared (1 N = 1 kgĀ·m/sĀ²). Roughly the weight of a small (100 g) apple under standard gravity, it is the base unit used throughout physics and engineering to express force, weight and thrust.
