Severity: wishlist
stat -f provides information on the filesystem, including block
sizes:
Block size: 4096 Fundamental block
size: 4096
The unit used in unfortunately not specified. Considering the fdisk
output I get...
Sector size (logical/physical): 512 bytes /
512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes
... I guess bits are the unit.
Note that the first measure ("Block size") is quite ambiguous.

has some block size terminology which might help (if that's indeed
the type of block we mean):
The basic block size (FFBS: Fundamental
Filesystem Block Size) used in the field table of this record is
the allocation unit used during file system creation. The number
of blocks that corresponds to the basic block size is called the basic block count. The
logical block size (PFBS: Preferred Filesystem Block Size) is the
allocation unit used during input/output operations. The number of
blocks that corresponds to the logical block size is called the logical block count.
