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 base unit for mass in the international system of units is kilogram while the standard unit for force is newton. One newton can be expressed in kilogram-force, which is roughly equivalent to 0.012. Since 1 gram is defined as 1/1,000th of a kilogram, 1 newton is approximately equal to 102 gram-force. Based on the United States customary system, 1 newton is also equivalent to 0.225 pound-force.
