    Annoyingly, each block is 512 bytes. (Why couldn't they just be 1k?)
    When I do the math, I just think of them as half a kilobyte:
    10,000 blocks * 1Kbyte/1024 bytes * 512 bytes / block =
    10,000 * 1/2Kbyte = 5,000 Kbytes
    So 10,000 "blocks" is about 5MB, depending on one's definition of "mega".
    -----------------------------------------------------------------------------------
    In Unix, a block has been a classic unit of measure, 512 bytes or
    1/2 Kbytes. So 10,000 blocks is 5,000K or 5 megs. The du command
    also measures disk space in 1/2K blocks.
