      1000kb = 1 mb So 894kb = 0.894mb or 0.894 of a meg.

      Re: kB/s ??????

      bits & bytes.........


      b = bit, kb = kilobit, Mb = megabit

      B = Byte, kB = kilobyte, MB = megabyte

      8 bits in a Byte.


      1 Mb = 1000000 bits

      1 kb = 1000 bits


      1 MB = 1000000 bytes (or 1048576 bytes)

      1 kB = 1000 bytes (or 1024 bytes)


      an e.g.

      "16 meg" broadband = 16 megabits per second = 16 mbps or 16 mb/sec

      = roughly 1.9 MBps = roughly 1953 kBps



      edit:

      so, 894 kB/s = over 7 megabits per second

      1 kB = 1000 bytes (or 1024 bytes)
      the SI standard unit for a Megabyte (MB) is 1000000 bytes. However I'm a traditionalist and still consider an MB to be 1024 KB which in turn is 1024 bytes.

      Note: if you have a connection speed of 9 mb/s don't expect downloads of 9000kb/s. Protocol overhead on a TCP connection on an ADSL link should roughly be around 50%. Based on for 64 KB of data you will have a TCP header, TCP Options, IP header, 2x AAL5 header and 2x ATM cell header.

      'Fraid not


      894 kB/s = 894 kilobytes per second


      Then, either (depending on if you use 1000 or 1024 - see the post by armitasp):

      a)

      894 * 1000 = 894000 bytes per second

      894000 * 8 = 7152000 bits per second

      7152000 / 1000000 = 7.152 mbps (mb/s, mb/sec, megabits per second)


      or b)

      894 * 1024 = 915456 bytes per second

      915456 * 8 = 7323648 bits per second

      7323648 / 1000000 = 7.32 mbps (mb/s, mb/sec, megabits per second).

      Lol oh dear my head is hurting!! I thought speed was measured in Byte's usually, M/Bytes K/Bytes etc. You are confusing me by introducing "bits"
      So if Sky say I have and 8mb connection that is:

      8 megabytes 8000 kilobytes 8000000 bytes right ? so where does "bit" fit into it all.
      I did all this theory about 25 years ago and I think some brain cells have died since then! Oh and its getting late!

      Which is why I said 894k is less than a megabyte 894000 bytes, less that a milion.

      Unless X 8 databits, but its not measured like that is it ???

      LOL, I know, it can be confusing, especially as many people think b & B are interchangeable, yet one means bit & one means byte.


      Size, storage space, whatever, is usually measured in bytes... kilobytes (kB), megabytes (MB), gigabytes (GB)... RAM, HDD size, etc etc.


      Speed is almost always in bits (per time).... kilobits (kb) per second, megabits (Mb) per second.....


      Ye Olde dial-up modems... 33.6kbps, 56 kbps (kilobits per second)

      Broadband... 512kbps, 1Mbps, 2Mbps, 8Mbps, 16Mbps, etc. etc.



      Your 8Mbps connection is 8 megabits per second (8Mbps, 8Mb/s, 8Mb/sec).

      8 megabits = 8000000 bits.


      There are 8 bits in a byte, so...

      8 megabits per second = 1 megabyte per second

      (however, that depends on how you class kilobytes & megabytes... 1000 or 1024, as mentioned previously, but it doesn't make too much difference)


      Although some things (browsers, torrent clients) may report a download speed using kilobytes/second (such as lopster's 894 kB/s [kilobytes/sec]....which is 0.894 MB/s [Megabytes/sec].... or over 7 Mb/s [Megabits/sec])



      Kilobit per second - Wikipedia, the free encyclopedia
      Megabit per second - Wikipedia, the free encyclopedia
