|Unit name||Newton meter|
|Physical quantity (s)||Torque , mechanical work|
|system||International system of units|
|In SI units|
|Derived from||Newton , meter|
According to the formatting rules of the International System of Units , the two unit symbols N and m must always be separated by a space or a multiplication point, but this space is not used in practice. The order of the factors should not be reversed in order to avoid confusion with mN = millinewtons.
Unit of energy
According to the definition , a newton meter is therefore equal to the units a joule and a watt-second of the scalar quantities energy , heat and work . A newton meter is the mechanical work that is done when the point of application of a force is shifted by one meter along its line of action by one newton . In practice, apart from intermediate calculation steps such as “… = 4711 N m = 4711 J” , the unit Newton meter is only used for torque, whereas Joule is used for energy, heat and work.
- 1 N m = 0.7375621 ft lb ( foot pound )
- 9.80665 N m = 1 kp m ( kilopond meter )
- 0.0980665 N m = 1 kg-cm ( kgf · cm )
