Quality of seeing

Could anyone out there explain to me the numbers I have read which refer to the quality of the seeing on any particular night. I'm sure I once read someone refer to his skies as a 5/10. Is the 5 a indication of the magnitude of the stars visible to the naked eye? What is the 10? I usually count the stars visible to my eye in the Little Dipper. It sometimes gets as low as three here in suburban Los Angeles.
