Applications of dimensional analysis

  • To convert a physical quantity from one system of units to the other:

    • This is based on a fact that magnitude of a physical quantify remains same whatever system is used for measurement. i. e.

    n1= Number value in (i) system

    n2= Number value in (ii) system

    M1= Unit of mass in (i) system

    M2= Unit of mass in (ii) system

    L1= Unit of length in (i) system

    L2= Unit of length in (ii… (272 more words) …
