Definition: The product of force and lever-arm distance, which tends to produce rotation. One newton metre is equal to the torque resulting from a force of one newton applied perpendicularly to a moment arm which is one metre long. The SI derived unit commonly use for torque is the newton metre. Alhough a newton metre is dimensionally equal to a joule (SI unit of energy and work), it is not appropriate to express a torque in joules. Energy and work is a scalar quantity while torque is a vector quantity (pseudovector).
To use the measurement conversion calculators simply enter a number value into the desired field and click calculate. All results shown will be equivalent values. Values are given to seven significant figures ( the odd result may show 9's or 0's over running). Values of 10 000 or greater will be displayed in the e-format e.g. 2.3456e7 which equals 2.3456 x 107 or 23 456 000. Values lower than 0.001 will be displayed in the e-format e.g. 2.3456e-5 which equals 2.3456 x 10-5 or 0.000 023456. The calculators require that your browser has java script enabled.
