118969 2003-02-07 02:29:00 Say I had a 100MB file that took 100 seconds to download...what equation would I use to work out the result in Megabits per second? Jar Jar Binks (633)
118970 2003-02-07 02:35:00 Multiply Bytes x 8 to get bits, so 100MB x 8 = 800Mb. Divide by time in seconds: 800Mb / 100 sec = 8Mb/sec. Note the capital B for Byte and lowercase b for bit. :| wuppo (41)
118971 2003-02-07 02:35:00 For MB per Second divide MBs by the number of seconds.

100mb / 100seconds = 1mb/s

100mb / 10 seconds = 10mb/s

100mb / 1000 seconds = .1mb/s

(QQ= Quite Quick).

Depends. I assume this is Ethernet, so it's roughly 8 Mbps. Must have been fairly big packet size. The Ethernet system does not use start/stop bits, but there are other overheads.
