tmpfs 248M 0 248M 0% /dev/shm

[root@server ~]# df -H

Rashed if you go to the man pages of df you will find your answer

-h, --human-readable
print sizes in human readable format (e.g., 1K 234M 2G)

-H, --si
likewise, but use powers of 1000 not 1024.

Both are correct but their representations are different.
