SI units of length, mass, time, electric current , temperature and amount of substance have to be listed and abbreviation has to be written for each SI unit. Concept Introduction: SI units refers to ‘International System of Units’ which have been used in the modern scientific calculations and metric system. It constitutes units of measurement of seven basic parameters – length, mass, time, electricity, temperature, amount of substance and luminous intensity. The SI unit of measurement must be written as symbol in lowercase but unit named after a scientist must be written with first alphabet as uppercase.
