Its a decaying average of the number of processes wanting the processor at the sample time along with those in "D" state which normally indicates an I/O wait. Its essentially an attempt to come up with one number that defines "busy-ness" There are better broken down stats available via vmstat, top etc but uptime does the job it was intended to do - it gives you a quick glance load assessment.
