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:
- The joule (J) is the SI unit of energy, and is the work done by a one-newton force acting over one meter.
- 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
- 1 N ≡ 1×105 dyne (symbol: dyn)
- 1 N ≈ 0.101972 kilogram-force (symbol:kgf)
- 1 N ≈ 0.101972 kilopond (symbol: kp)[note 1]
- 1 N ≡ 1×10-3 sthène (symbol: sn)
- 1 N ≈ 0.224809 pound-force (symbol: lbf)
- 1 N ≈ 2.24809×10-4 kip (symbol: kip)[note 2]
- 1 N ≈ 7.233014 poundal (symbol: pdl)
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).
- Another name for a kilogram-force. Not to be confused with "kilopounds", meaning 1,000 pounds of mass.
- A non-SI unit of force equal to 1,000 pound-force.
