  1. It is defined as that force necessary to provide a mass of one kilogram with an acceleration of one metre per second per second. One newton is equal to a force of 100,000 dynes in the centimetre-gram-second (CGS) system, or a force of about 0.2248 pound in the foot-pound-second (English, or customary) system.

    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.
