Concept Introduction:
Dimensional analysis is a way to interpret and convert units of measurement of a physical quantity and to find the relationship between them. A prediction of the relationship between units is to be made in order to convert one unit to another.
Conversion factor is a number which helps change one set of units to another by division or multiplication.
The conversion factors are as:
