side note: while what rindi said is mostly true, ( the standard ups's that you get for a pc. etc., there are ups's that are set up to keep equipment up for long periods of time.
for example: our EATON ups will keep our servers and it department up and running for approximately 3 to 5 hours, depending on the load.

I would also derate 3 times:
1. Once to compensate for power factor, since most loads are not reactive.
2. Once to allow for battery age, maybe 20%.
3. Another 20%, because UPS manufacturers tend to overrate.
