Converting kilometers to micrometers

  1. Aug 20, 2008 #1
    1. The problem statement, all variables and given/known data
    how many microns make up 1 K.m


    2. Relevant equations
    prefixes for SI units


    3. The attempt at a solution
    i really can't attempt it because i have no idea what to do, i forgot how to do this stuff

    Why don't you look up what a micron is first? Then km as well. And figure out how many of one is in the other?

    I'm starting to have problems taking you seriously.

    one micron equals 10^-6 meters and 1 km equal 10^3 meters

    10^9 microns equal 1 km

    1,000m/1km * 1 micro u/1*10^-6=10^9

    It equal 10^9 or 1,000,000,000

    Sure thing. That wasn't so hard, was it?

    No it wasn't. I'm very rusty on my physics and Calculus.

    Practice makes perfect. You might try finding a book with solutions and practicing offline. I don't think all of these problems need posting.
