Thanks for the report.  According to 'dd --help', "MB 1000*1000, M
1024*1024", so the result matches documentation.  However, some of the
coreutils (such as ls) support --human-readable vs. --si to choose between
power of 10^3 and power of 2^10, maybe it would be worth adding such an
option to dd.

Also, you may want to consider upgrading - the latest stable version is 6.7.
