I think all of you need to know about the "convert" command ;)

e.g. to do the above conversion correctly:

xfs_db> convert daddr 660 fsb
0x52 (82)

The xfs_db man page tells you all the different formats that can
be converted between. The convert command automatically takes into
account the geometry of the filesystem where appropriate (e.g.
filesystem block size).

Cheers,

Dave.
