siunitx package definitely. – azetina Nov 1 '13 at 21:02
Do I have to download that? I mean, I'm completely new to LaTeX. – David O'Sullivan Nov 1 '13 at 21:04
Try \si{kg.s^{-1}} by loading the package siunitx. – azetina Nov 1 '13 at 21:05
I suppose you have miktex or texlive right? If so then download the package via the tlmgr(texlive) or package manager(miktex). – azetina Nov 1 '13 at 21:06
Please have a look to question tex.stackexchange.com/questions/2063/… – Kurt Nov 1 '13 at 21:23

The siunitx package will interpret the units correctly

enter image description here

\si{\kilogram\per\second} \\
