Physical constants

    1. The problem statement, all variables and given/known data
    What is the difference between a dimensional physical constant and dimensionless physical constant?

    2. Relevant equations


    3. The attempt at a solution

    Please fill all the templates.You will have to show some effort in order to get any help.In physics terms I would say
    "The results you achieve is directly proportional to the effort you apply"

    Maybe start out with examples of each type of constant?

    What is the context of your question ? In introductory physics there are hardly any dimensionless physical constants, apart from ratios.
    Are you sure you don't mean coefficients (e.g. for physical properties, friction coefficients and such) ?

    If we leave out a whole lot of ratios (mostly dimensionless for obvious reasons),
    when I look at a list , all I see are physical constants with a dimension -- apart from a few very fancy ones such as ##\alpha## and g-2 .

    I think they mean something like π or e

    nR, what DO you mean ? I read physical constants.
