Subject: what is the strenght-weight ratio of titanum compared to other steels e.t.c

I am a first year engineering studnt who has met a contradiction, I have 
read that titanium is not as higher strength-weight ratio(for want of a 
better word)as say, carbon fibre or other steels, such as high carbon 
steels. BUT I have also heard that it has a very high strength-weight 
ratio. could you please help me here with this queriry? Thanks, TOM :-)
