The unit is also used less commonly as a unit of work, or energy, in which case it is equivalent to the more common and standard SI unit of energy, the joule. One newton-metre is equal to the torque resulting from a force of one newton applied perpendicularly to the end of a moment arm that is one metre long. The newton-metre or newton-meter (also non-hyphenated, newton metre or newton meter symbol N⋅m or N m ) is the unit of torque (also called moment) in the International System of Units (SI).

Learn more about the Road to the Revised SI.The changes became effective on World Metrology Day, May 20, 2019. Redefining the SI – In November 2018, the world’s measurement experts voted and unanimously approved a revision of the SI that establishes a measurement system entirely based on physical constants of nature.Here h W is the physical quantity, its value expressed in the unit 'meter,' unit symbol m, is 169 m, and its numerical value when expressed in meters is 169. Example: the value of the height h W of the Washington Monument is h W = 169 m.Thus, the numerical value of a particular physical quantity depends on the unit in which it is expressed. The value of a physical quantity is the quantitative expression of a particular physical quantity as the product of a number and a unit, the number being its numerical value.A unit is a particular physical quantity, defined and adopted by convention, with which other particular quantities of the same kind are compared to express their value.A physical quantity is a quantity that can be used in the mathematical equations of science and technology.Examples are the mass of the moon and the electric charge of the proton. A quantity in the particular sense is a quantifiable or assignable property ascribed to a particular phenomenon, body, or substance.National Type Evaluation Program (NTEP)Ī quantity in the general sense is a property ascribed to phenomena, bodies, or substances that can be quantified for, or assigned to, a particular phenomenon, body, or substance.National Conference on Weights and Measures (NCWM).External Resources for Weights and Measures Expand or Collapse.Fuels and Lubricants Subcommittee (FALS).National Legal Metrology Expand or Collapse.
