The newton is the SI unit of force, and is the force that will accelerate 1 kilogram one metre per second per second. The symbol of the newton in SI is N. The newton is also the unit of weight.

The newton is named for Isaac Newton (1643 - 1727), who developed the laws of motion in classical mechanics.

The newton is a derived unit in the SI:

Related units

  • The joule (J) is the SI unit of energy, and is the work done by a one-newton force acting over one meter.

  • The watt (W) is the SI unit of power, and is the power that gives rise to one joule in one second.

  • The pascal (Pa) is the SI unit of pressure, and is equal to a one-newton force acting over an area of one square metre.

  • The newton-metre (N·m) is the SI unit of torque, and is the amount of torque generated by one-newton force acting at a radius of one metre. There is no distinct name for this unit.

Equivalent units of force

Practical use

A kilogram mass has a weight of about 9.81 N in earth's surface gravity. A healthy adult human subject to earth's surface gravity typically weighs between 450 N and 900 N.

The drive train of a 2006 Chevrolet Corvette Z06 can produce approximately 10.3 kN while accelerating the car from 0 to 26.8 m/s (60 miles per hour).

Notes

  1. Another name for a kilogram-force. Not to be confused with "kilopounds", meaning 1,000 pounds of mass.
  2. A non-SI unit of force equal to 1,000 pound-force.
