| Measures and Units: newton |
[Etymology: I. Newton; England 1642-1727] force. Symbol N. SI, Metric-m.k.s. Identically kg·m·s-2, i.e. the force that gives to a mass of 1 kilogram an acceleration of 1 metre per second, per second (= m·kg·s-2 in base terms). The following are among the coherent derived units:
• N·m for moment of force;
• N·m = joule for energy, work, quantity of heat;
• N·m·s-1 = watt for power, radiant flux;
• N·s·m-2 for dynamic viscosity;
• N·m-1 for surface tension;
• N·m-2 = pascal for pressure.
The name was advocated in 1935
[Hartshorn L., Vigoureux P. Nature Vol. 136, 397 (1935)] and soon became accepted generally.
