How to read a specific type of dimensional analysis

  1. May 21, 2012 #1
    1. The problem statement, all variables and given/known data



    2. Relevant equations



    3. The attempt at a solution

    In some work I have been following, I keep seeing notation like:

    for energy .... [tex]ML^2 T^{-2}[/tex]

    How is this supposed to be read? I understand this is using mass, length and time, but what is it saying? Would I be right in thinking it says

    ''mass times length squared divided by time squared?''

    As soon as I understand that, I think I will understand how to read this kind of notation

    Thanks in advance!

    hi help1please! :smile:
    exactly! :smile:

    (and that tells you that in SI units it will be in kg m2 s-2, ie J)
