Homework Help: Unit Conversion

  1. Jul 26, 2011 #1
    1. The problem statement, all variables and given/known data
    "The gravitational constant G is 6.67*10^-11 m^3*s^-2*kg^-1. What is G in units of cm^3*s^2*g^-1

    2. Relevant equations
    1kg = 1000g
    1m = 100cm

    3. The attempt at a solution

    I don't understand how the dimension can change from [L^3,T^-2,M^-1] to [L^3,T^2,M^-1], shouldn't the dimension stay consistent even if the units change?

    Yes, it's a typo, they are missing a minus sign on that "s" exponent.
