Homework Help: M/s^2 to km/h^2 conversion

  1. Aug 10, 2006 #1
    The question is to convert:
    8.4 m/s^2 into km/h^2
    I did:
    8.4m/s(1000km/1m)(3600s/1h)= Wrong.
    lol So what didn't I do right? I cancled out the m and s for km and h but according to my book this is wrong?

    The units of time are squared, so you might need to take that into account with your time conversion.

    8.4 m/s^2 into km/h^2
    =108864 km/h^2

    Pencil I belive that your probleme (aside from the squares) was that 1000m=1km and not 1000km=1m.
