The newton (abbreviation and symbol: N) is the unit of force in metric system (SI), named after Isaac Newton. The newton is equal to the amount of force needed to accelerate a one kilogram mass at a rate of one meter per second squared. 1 newton (N) = 0.224808943 pounds force (lbf) = 0.101971621 kilogram-force (kgf) Report an error on this page.
The pound unit gets confusing, as there are several definitions related to separate terms like lbf, lbm, poundals, etc. For most physics problems using newton's laws, pound is defined as unit of force, used primarily in the USA. In the SI system, the force unit is the Newton. 1 kg weighs 9.8 newtons, or 2.2 pounds, more or less. That's a conversion factor used to equate mass with weight on planet Earth.
