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?
Thanks

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
8.4m/s^2(1km/1000m)(3600s/1h)^2
=8.4*3600*3600/1000
=8.4*3.6*3600
=30.24*3600
=108864 km/h^2

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