Megabytes to Kilobytes

  1. Dec 29, 2008 #1
    simple questions:

    How many kilobtyes are in a megabyte, and how do you explain this?

    and

    If i have, lets say, 178,000 kilobytes how many megabytes would this translate to? and how can it be explained?

    It's a tricky question.
    Technically kilo means 1000 and mega means 1,000,000
    But in computers it's often easier to talk about multiples of 1024 so in general speak a kilobyte is 1024 bytes. Techncially this should be called a kibobyte (kibo=1024).

    Then you get into marketing speak, hard drives that are sold as 100Mega bytes will often be 100,000,000 bytes - the computer working in kibobytes will list this as only 95Mb ie. 100,000,000 / (1024*1204)

    So 178,000kb could be 178Mb or 173.8Mb depending
