This whole thread is confusing to me as well. Isn't the whole point of a kibibyte to work in increments of 1024, unlike kilo, which is actually 1000, as defined by the sciences long ago?
So 1024 * 256 is 256 KiB by definition, since a Kibibyte is literally 1024 bytes, and the number of Kilobytes will by higher, since the number it represents is smaller.
Either user a1369209993 is unaware of the distinction ( https://en.wikipedia.org/wiki/Kibibyte ) or then they are deliberately ignoring it (My guess: to defend the old definition of kilobyte = 1024 bytes) to the point that their messages look like trolling.
That's what I thought. I really only care about how much "stuff" I can store in a block, which is 1,024 bytes. If that's 1KiB or 1.024KBs, the distinction isn't worth that much brainpower.
