jelwell Posted September 7, 2009 CID Share Posted September 7, 2009 Someone please define: Kbps kB/s I thought Kbps means 1000 bits per second, and I thought kB/s equals 1000 bytes (8 bits) per second. My recent upload test result is: 1185 Kbps or 1.2 Mbps (145 kB/s) However when I divide 1185 Kbps by 8 bits, the result is 148.125 bytes per second and not 145 kB/s. Also, I believe 1024 bytes equal one kilobyte. So, 145 kB equals 148480 bytes, and that times 8 bits per byte equals 1187840 bits and not 1185 kilobits. So no matter how I calculate, 1185 Kbps doesn't seem to equal 145 kB/s. Help! Quote Link to comment Share on other sites More sharing options...
tommie gorman Posted September 7, 2009 CID Share Posted September 7, 2009 Try this. http://en.wikipedia.org/wiki/Data_rate_units#.27b.27_vs_.27B.27 Quote Link to comment Share on other sites More sharing options...
RTB Posted September 7, 2009 CID Share Posted September 7, 2009 The trick is that the connection speed (the kbps/mbps number) uses base 10 for the prefixes, while the download speed (to harddisk for example) uses base 2. Thus to go from kbps to KB/s (should actually be KiB/s) you divide by 8.192. Quote Link to comment Share on other sites More sharing options...
