Quick question: Conversion

  1. Apr 24, 2012 #1
    1. The problem statement, all variables and given/known data

    I want to know if my conversions seem correct to you:

    If 1nm = 10^-9, then...

    0.1nm = 10^-10 ?

    520nm = 5.2 x 10^-7 ?

    Yes. To get from the first equation to the 2nd one, you divided both the LHS and RHS by 10

    520nm = 520 x 10^-9 = 5.2 x 10^-7

    Yes. To convert from the 2nd quantity above to the 3rd quantity, you divide 520 by 100, and multiply 10^9 by 100 to keep the same value for the full quantity.
