Newton (unit) - Wikipedia
The newton (symbol: N) is the unit of force in the International System of Units (SI). It is defined as $${\displaystyle 1\ {\text{kg}}\cdot {\text{m/s}}^{2}}$$, the force which gives a mass of 1 kilogram an acceleration of 1 metre per second squared. It is named after Isaac Newton in recognition of his work on classical mechanics, … 展开
A newton is defined as $${\displaystyle \mathrm {1\ kg{\cdot }m/s^{2}} }$$ (it is a named derived unit defined in terms of the SI base units). One newton is, therefore, the force needed to 展开
Large forces may be expressed in kilonewtons (kN), where 1 kN = 1000 N. For example, the tractive effort of a Class Y steam train locomotive and the thrust of an F100 jet engine are both around 130 kN.
