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.
A force of one newton will accelerate a mass of one kilogram at the rate of one meter per second per second. The corresponding unit in the CGS system is the dyne; there are 105 dynes in one newton. In traditional English terms, one newton is about 0.224 809 pounds of force (lbf) or 7.233 01 poundals.
