The value of any physical quantity is always expressed as its numerical value as well as a unit. One often hears the weight expressed as grams or kilograms; the distance as foot, yard or mile; the volume as litres or gallons. The use of a number of units cause confusion and comp..

Unit work is the amount of work done when a unit force displaces a body through unit distance in the direction of the force. In International System of units, the absolute unit of work is 'joule'. 1 joule = 1 newton x 1 met..

The most common unit for mass is expressed in grams (g) or kilogram (kg) (1 kg = 10 3 g). In chemical measurement, IUPAC prescribes that the mass of a gas (m) be expressed in terms of the number of moles (n). The number of moles can be obtained from the mass of the gas using the relation..
