I mentioned this to you a couple of weeks back but perhaps you missed it. The abbreviation for kilometer (and it's official) is km, not kl. Try not to work so HARD at looking like a fool. Additionally, while written out numerically one can say 2 million km^2, in text, one uses the term "square kilometers". The value you've actually expressed by saying 2 million kl (sic) squared is 4 trillion kilometers.
