The newton (symbol: N) is the SI unit of force. It is named after Sir Isaac Newton [1] in recognition of his work on classical mechanics [2].
Definition[]
A newton is the amount of force requiAred to accelerate a mass of one kilogram at a rate of one meter per second squared. In addition, 1N is the force of gravity on a small apple on Earth.
- 1 N = 1 kg•m/s2
Conversions
| (SI unit | Dyne | Kilogram-force | (Kilopond) | Pound-force | Poundal |
|---|---|---|---|---|---|
| 1 N | = 105 dyn | = 1 kg•m/s² | ˜ 0.10197 kp | ˜ 0.22481 lbf | ˜ 7.2330 pdl |
| 1 dyn | = 10−5 N | = 1 g•cm/s² | ≈ 1.0197×10−6 kp | ≈ 2.2481×10−6 lbf | ≈ 7.2330×10−5 pdl |
| 1 kp | = 9.80665 N | = 980665 dyn | = gn•(1 kg | ≈ 2.2046 lbf | ≈ 70.932 pdl |
| 1 lbf | ≈ 4.448222 N | ≈ 444822 dyn | ≈ 0.45359 kp | = gn•(1 lb) | ≈ 32.174 pdl |
| 1 pdl | ≈ 0.138255 N | ≈ 13825 dyn | ≈ 0.014098 kp | ≈ 0.031081 lbf | = 1 lb•ft/s² |
The value of gn as used in the official definition of the kilogram-force is used here for all gravitational units.
This SI unit is named after Isaac Newton. As for all SI units whose names are derived from the proper name of a person, the first letter of its symbol is uppercase (N). But when an SI unit is spelled out, it should always be written in lowercase (newton), unless it begins a sentence or is the name "degree Celsius".
— Based on The International System of Units, section 5.2.[3]
Non-SI units of force[]
- Dyne, the unit of force of the (mostly obsolete) CGS system, equal to 10 µN.
