BPM is beats per minute, so for example:

60 bpm means 60 beats in 1 minute, 1 beat per second

120 bpm is 120 beats in a minute, 2 per second, or better one every 0.5 
seconds

Generalising:

seconds = 60 / bpm

Or also (probably more useful in Pd related stuff)

milliseconds = 60000 / bpm

Lorenzo.
PS: see attached patch for a simple implementation I've often used ;)
