top - Load average

Hello, Here is the output of top command. My understanding here is,
the load average 0.03 in last 1 min, 0.02 is in last 5 min, 0.00 is in last 15 min.

By seeing this load average, When can we say that, the system load averge is too high?
When can we say that, load average is medium/low??

15:18:58 up 404 days, 17:54, 1 user, load average: 0.03, 0.02, 0.00
225 processes: 224 sleeping, 1 running, 0 zombie, 0 stopped
CPU states: cpu user nice system irq softirq iowait idle
total 1.2% 0.0% 0.5% 0.0% 0.0% 0.2% 97.9%
cpu00 0.5% 0.0% 0.1% 0.0% 0.0% 0.7% 98.4%
cpu01 0.0% 0.0% 0.7% 0.0% 0.0% 0.1% 99.0%
cpu02 4.1% 0.0% 1.5% 0.0% 0.0% 0.0% 94.2%
cpu03 0.1% 0.0% 0.0% 0.0% 0.0% 0.0% 99.8%
Mem: 5907464k av, 5875112k used, 32352k free, 0k shrd, 156876k buff

I would appreicate if any one can answer for this. Thanks

NAME
uptime - Tell how long the system has been running. SYNOPSIS
uptime [options] DESCRIPTION
uptime gives a one line display of the following information. The current time, how long the system has been running, how many users are currently logged on, and the system load averages for the past 1, 5, and 15 minutes. This is the same information contained in the header line displayed by w(1). System load averages is the average number of processes that are either in a runnable or uninterruptable state. A process in a runnable state is either using the CPU or waiting to use the CPU. A process in uninterruptable state is waiting for some I/O access, eg waiting for disk. The averages are taken over the three time intervals. Load averages are not normalized for the number of CPUs in a system, so a load average of 1 means a single CPU system is loaded all the time while on a 4 CPU system it means it was idle 75% of the time. OPTIONS
-p, --pretty show uptime in pretty format -h, --help display this help text -s, --since system up since, in yyyy-mm-dd HH:MM:SS format -V, --version display version information and exit FILES
