1.6.19-1.EL had "standard" binary kB and mB.

1.8.1-17.el5 (CentOS 5.2), presumably a newer version, went to the
decimal-only kB and mB. There were a lot of other format changes in output,
too. We are on top of them, but decimal-only kB and mB is really a bad idea,
since it's inconsistent with all previous practice and also with sectors.
