From the man page of resize2fs command, a pearl:
Note: when kilobytes is used above, I mean real, power-of-2 kilobytes, (i.e., 1024 bytes), which some politically correct folks insist should
be the stupid-sounding ``kibibytes''. The same holds true for
megabytes, also sometimes known as ``mebibytes'', or gigabytes, as the
amazingly silly ``gibibytes''. Makes you want to gibber, doesn't it?
Oh man, not only gibber, laughing hard...
