Newton metre is the unit of moment in the SI system. It is abbreviated N m or N·m, and sometimes hyphenated newton-metre. It is a compound unit of torque corresponding to the torque from a force of one newton applied over a distance arm of one metre. The definition, agreement and practical use of units of measurement have played a crucial role in human endeavour from early ages up to this day. ... In physics, the moment of force (often just moment, though there are other quantities of that name such as moment of inertia) is a quantity that represents the magnitude of force applied to a rotational system at a distance from the axis of rotation. ... The International System of Units (abbreviated SI from the French language name Système International dUnités) is the modern form of the metric system. ... In physics, torque can be thought of informally as rotational force. Torque is measured in units of newton metres, and its symbol is Ï„. The concept of Torque, also called moment or couple, originated with the work of Archimedes on levers. ... In physics, a force is an external cause responsible for any change of a physical system. ... The newton (symbol: N) is the SI unit of force. ... The metre (Commonwealth English) or meter (American English) (symbol: m) is the SI base unit of length. ...

While a newton metre is dimensionally equivalent to a joule, the SI unit of energy and work, in a newton metre, the force and the distance arm are normal to each other, while in the joule, force and distance are co-linear. The joule (symbol: J) is the SI unit of energy, or work. ... The International System of Units (abbreviated SI from the French language name Système International dUnités) is the modern form of the metric system. ...

The metre, or meter (symbol: m) is the SI base unit of length. ... The deprecated unit kilogram-force (kgf) or kilopond (kp) is the force exerted by one kilogram of mass in standard Earth gravity (defined as exactly 9. ... The metre, or meter (symbol: m) is the SI base unit of length. ... In physics, a foot-pound force (symbol ft·lbf or ft·lbf), usually abbreviated to foot-pound, is an Imperial and U.S. customary unit of mechanical work, or energy, although in scientific fields one commonly uses the equivalent metric unit of the joule (J). ... The pound-force is a non-SI unit of force or weight (properly abbreviated lbf or lbf). The pound-force is equal to a mass of one pound multiplied by the standard acceleration due to gravity on Earth (which is defined as exactly 9. ...
