I had a test when i was in 9th grade for computer( not computer programming )

Q) how many KB are i an MB ?
1) 500 2) 1000 3) 2000 4) none of the above

Since its 1024 i thought its none of the above like a sane person but my teacher be like " there are 1000 KB in 1 MB." I tried to explain that i think thats wrong but well gg.

    If it was Kb then that would be right.

    1000 kilobits = 1 megabit

    No i am pretty sure it was byte as while talking i guess she mentioned " 1000 and 1024 is the same thing " FUCK NO.@mrstebo

    kb != kib
    but this confuses me too every time.

    in my last test this question was not possible, because the answer would be written in there.

    Well but 1000is the right answer. If it were KiB to MiB 1024 would be correct

    I still curse those evil scientists who felt the need to change the convention

    Now(since long time)
    1 MB = 1000 KB
    1 MiB = 1024 KiB

    People of all kind confuse the terms and use them interchangeably. I've read college grade books (official literature recommend by professors) that messed it up.
    Still remember the shock when I realized the diff.
    Fucking HDD manufacturers!

    Just to clarify back then in India (10 yrs ago) in my book 1KB was 1024 byte same with MB so pretty sure my professor messed up@nnee

    What's important is whether there's an i. It defines what base the factor has.
    KiB (Kibibyte) => 2^10 Bytes whereas KB (Kilobyte) => 10^3 Bytes.
    MiB (Mebibyte) => 2^20 Bytes and MB (Megabyte) => 10^6 Bytes. Take a look at https://en.wikipedia.org/wiki/.... This is why eg an 100GB drive only shows as 98GB or so when mounted

    What @erroronline1 said.
    Your teacher was right and you were wrong. KB is used imo for a better Marketing.
    The regular consumer would be easily confused with e.g. 4096 GB etc.

    As i said, there seems to be a change in the convention but this test is around 10 yrs old and i am pretty sure my book at the time said KB being 1024@-ANGRY-CLIENT-

    There is never a reason to use 1000 when referring to measurements of data.

    The correct answer should always be 1024.

    @Root I kind of disagree because using kB for 1024 is misusing established SI prefixes. I always try to use KiB for that reson when writing. However when talking I still use "kilobyte" instead of "kibibyte" which sounds strange and will give you mostly confused looks.

    @bootleg-dev I'll concede that point because the inconsistency really bothers me, too.

    (And who came up with "mebibyte" anyway?!)

    But really, there is zero use for multiples of 1000 bytes for anything other than marketing bs.
