data rate conversion for f4fpackager

Hello,

I am woundering what Adobe suggest in the following matter. So, when I use f4f packager command line tool,i supply --bitrate value, but I know it in bps (say 500,000 bps). And f4fpackager wants it in kbps. So, should I divide by 1024 or 1000? Does that matter as far as that switching point for client logic? What would Adobe recommend?
