Physical quantities/ magnitudes

  1. Aug 28, 2011 #1
    I've seen that in English you refer to the measurable physical properties as http://en.wikipedia.org/wiki/Physical_quantity" [Broken], but some sites call them "physical magnitudes". Are both of them correct?. Do you consider them as synonyms?

    In Spanish we say "magnitudes físicas", and I wonder if "physical magnitudes" is a bad translation from Spanish.

    Thanks in advance!

    In general "quantity" is a more general term, while "magnitude" is more specific. Example, one property of an object is that is has a mass (quantity) - specifying it is 10 kilos defines the magnitude.
