Newton (N)
The newton (N) is the SI unit of force: the force that accelerates 1 kg at 1 m/s². A 1 kg mass weighs about 9.81 N.
Symbol: N
Quantity: force
SI relation: N is the coherent SI unit of force.
Derivation: 1 N = 1 kg·m/s²
Exact: yes, by definition
History
Named after Isaac Newton; adopted for the kg·m/s² by the 9th CGPM in 1948.
Typical uses
- Engineering loads and reactions
- Spring and actuator forces
- Tensile test forces (kN)
