I see that you noticed you had an alias with -T, so deleting my explanation for that. :) The block size discrepancy has a history behind it [1]. Myself, and likely most other people, prefer 1024 byte blocks. People who have other preferences can do either of the following: $ POSIXLY_CORRECT= df | head -n 1 Filesystem 512B-blocks Used Available Use% Mounted on $ df --block-size=512 | head -n 1 Filesystem 512B-blocks Used Available Use% Mounted on Collin [1] https://en.wikipedia.org/wiki/POSIX#512-_vs_1024-byte_blocks
