RPi normally is consuming about 2W (if it doesn't have to power
anything via USB), so way under 0.5% of an average UPS.
Couple of weeks ago when I was running my tests nut at RPi was reliably
reporting the about 33% of load I have on my UPS (for the time being I
have also a cheap kill-a-watt meter on the UPS input):
