S I UNITS This unit is an extension of the traditional metric system (MKS-Metre KilogramSecond). In 1950 the International Electro-chemical Commission (IEC) adopted ‘ampere’ – the electric current as the fourth basic unit besides Metre, Kilogram and Second of MKS being called as MKSA system. The General Conference on Weights and Measures (Conference Generale des Poids et Measures CGPM) in 1954 adopted the unit of luminous intensity of light as ‘candela’ besides degree kelvin for temperature. India adopted Metric System through statutory decision by an Act of Parliament in 1956 to change over to MKS system. In 1960 at the 11th meeting of CGPM a more coherent unit, syste’me International d’ Unite’s abbreviated as SI, was adopted. In it the energy, heat and work are expressed in terms of a single unit, joule eliminating the use of Joule’s conversion factor. Many countries have adopted this system since then. The British Government adopted this unit on 24th May, 1965. SI units are grouped into three classes: 1.Basic Units: It is based on seven standard dimensions independent of each other as listed in Table SI-1. 2.Supplementary Units: As the General Conference has not classified certain units of the International System either in basic units or derived units, they are grouped as supplementary units as listed in Table SI-2. 3.Derived Units: There are some derived units in terms of basic units used to indicate a physical quantity. As an example, unit of energy is expressed as kg.m2 /s2 which is represented by joule having symbol J. Similarly force has a unit of kg.m/s2 and is expressed as newton having symbol N. A set of such special names with their symbol and units are given in Table SI-3. It is to be noted that the unit representing certain physical quantity should be written with small letter, even though they are representing well known names of the leading inventors. As an example Watt, Kelvin and Newton used to denote energy, temperature and force should be written as: watt, kelvin and newton. There are several other common derived units expressed in terms of basic and derived units with special names. They are listed in Table SI-4.

In India quintal is most commonly used which amounts to 100 kg. Pressure is also expressed in bar which is equivalent to 105 N/m2 or 105 Pa or 102 kPa or 0.1 MPa. Volume is also expressed in litre (L) as special case. It represents cubic decimetre. It is restricted to the use of volume for liquid and gas. One may use milli- and micro- with litre but not other prefixes. Prefixes: The prefixes are used to keep the variation in physical quantities between 0.1 and 1000. Hence one may write 1000 N as 1 kN and 1,00,000 N as 0.1 MN. But compound prefixes are not permitted in SI Unit. As an example, 106 W = 1 kkW is not permitted. It has to be used as 1 MW. Similarly 107 Pa should be written as 10 MPa and not as 10 k.k.Pa. 105 Pa may be written as 0.1 MPa. Some unit symbols which are under common use in SI system these days, are h for hour, min for minute (1 min ≡ 60 s), d for days, t for metric ton (=1000 kg), ha for hectare (10,000m2), kWh for kilowatt-hour (=3600 kJ or 3.6 MJ).
