Hello,
I searched the forum but didn't find what I'm looking for.
How many kbps does 6.5 MiB/s correspond to (I'm specifying it's MiB)?
Thank you

Configuration: Windows 7 / Firefox 12.0

    There is not a huge difference between the two. (Purists will say there is...)
    In fact, one is calculated in powers of 2 and the other in powers of 10.

      When you start talking terabytes or even gigabytes, yes, I assure you that makes a hell of a difference.

      And here we go... a purist... lol
      Bring that back to % and it doesn't change much...
      On the other hand, it's true that if it were in Euros on my salary, it would be different... lol
      That said, machines only understand binary... so for me it will always be:
      1 kB = 1024 B and 1 kbit = 1024 bits...
      Not to be confused with kB (for the uninitiated) => 1 kB = 1 kB (B for byte in English, byte = octet) => the trick of ISPs to make us dream with the speeds... (they talk to us about mbits/s so that we understand MB/s...)

      Meh, a 1TB hard drive will actually only provide about 930GiB, which makes a difference. 7% is not insignificant.

      Furthermore, outside of Windows, all OSes clearly distinguish between kB and KiB.

      And to play the purist to the end, a Byte does not mean octet; it is the smallest addressable unit. It turns out that on a PC, a byte is almost always 8 bits, but that’s not necessarily the case. ;-)

      Not a purist. Precise. Computing is a world of precision and it's important to use the right terms to progress.

      Aren't you the one who wanted to get your site hacked?

      No,
      once again, 1 Kbit/s is 1000 bits/s, it's a speed, not a memory size.
      Operators have always expressed their speeds in Kbit/s, so multiples of 1000, not to deceive people but simply because that's the measure:

      http://sebsauvage.net/comprendre/provider/provider_modem.html
      http://arsene.perez-mas.pagesperso-orange.fr/signal/numerisation/numerisation_standards_son.htm
      an ethernet port is not 10 Mibibit/s but 10000000 bit/s
      It's a stupid drift to reduce everything in computing to units of 1024.
      Telecoms have joined computing, but not necessarily their bad practices.

    1 MiB = 2^20 bytes (1,048,576 bytes)
    1 byte = 8 bits
    1 kbit = 1024 bits
    It's up to you to continue........

    And you probably didn't have to search that much.... => https://fr.wikipedia.org/wiki/Octet

    Thank you for your responses, but it's just that unlike the classic Mo, it is marked Mio, hence my question.

    Okay, thank you.
    So that should be around 6000 kb/s.

      no,
      it's the other way around:
      6.5 MiB represents 6.5x2 ^20 bytes or 6.5x1,048,576 or 6,815,744 bytes
      So 6.815 MB or 6815 KB
      Got it?

    Yes, you wrote 1Mio=1.048.576 while 1Mio=1.000.000 bytes; do not confuse Mio and Mo.

      Well, actually no. According to the standard set in 1998 by the International Electrotechnical Commission, it's the opposite. See the wiki page => https://fr.wikipedia.org/wiki/Octet
      In fact, apparently we (including myself) all make the mistake...
      The standard defines that:
      1 kB = 1000 bytes (I know, it shocks me too... lol)
      1 KiB = 1024 bytes

      Why does it shock you that a kilogram is 1000, cooyoo?
      Let's note in passing that indicating a rate in binary units makes no sense on a serial link.
      It only has significance for memory sizes or anything organized in tables of sizes that are multiples of the powers of two.
      A serial stream is not related to the powers of two and no manufacturer indicates rates in MiB, because the number is less advantageous (with one MiB containing more data than one MB).

    It’s just a matter of nuance: 1Mio = 1 million bytes, that is to say based on a thousand and not 1024.

      And did I write anything else?
