-size n[cwbkMG]
              File uses n units of space.  The following suffixes can be used:

              `b'    for  512-byte blocks (this is the default if no suffix is
                     used)

              `c'    for bytes

              `w'    for two-byte words

              `k'    for Kilobytes (units of 1024 bytes)

              `M'    for Megabytes (units of 1048576 bytes)

              `G'    for Gigabytes (units of 1073741824 bytes)

              The size does not count  indirect  blocks,  but  it  does  count
              blocks in sparse files that are not actually allocated.  Bear in
              mind that the `%k' and `%b' format specifiers of -printf  handle
              sparse   files  differently.   The  `b'  suffix  always  denotes
              512-byte blocks and never 1 Kilobyte blocks, which is  different
              to the behaviour of -ls.
