How can I tell how bad my vision is from my contact lens prescription?

The prescription for my right eye says -5.5 and for my left it says -4.75. What does this even mean and where does this fit in with the whole 20/20 thing? I know my vision is pretty bad because without contacts or glasses I can barely recognize people from like 5+ feet away. I know to be legally blind it has to be 20/200 but how can I figure that out?
