These things are horrible, but I've seen them beginning to be used.

"In December 1998 the International Electrotechnical Commission (IEC), the
leading international organization for worldwide standardization in
electrotechnology, approved as an IEC International Standard names and
symbols for prefixes for binary multiples for use in the fields of data
processing and data transmission. The prefixes are as follows:
------------------------------------------------------------------------
Prefixes for binary multiples
------------------------------------------------------------------------

�Factor� Name�  Symbol�  Origin   Derivation�
�2^10    kibi    Ki    kilobinary: (2^10)^1    kilo: (10^3)^1
�2^20    mebi    Mi    megabinary: (2^10)^2�    mega: (10^3)^2
�2^30    gibi    Gi    gigabinary: (2^10)^3    giga: (10^3)^3
�2^40    tebi    Ti    terabinary: (2^10)^4    tera: (10^3)^4
�2^50    pebi    Pi    petabinary: (2^10)^5    peta: (10^3)^5
�2^60    exbi    Ei    exabinary: (2^10)^6    exa: (10^3)^6
------------------------------------------------------------------------
Examples and comparisons with SI prefixes
one kibibit    �1 Kibit = 2^10 bit = 1024 bit
one kilobit    �1 kbit = 10^3 bit = 1000 bit
one mebibyte    �1 MiB = 2^20 B = 1 048 576 B
one megabyte    �1 MB = 10^6 B = 1 000 000 B
one gibibyte    �1 GiB = 2^30 B = 1 073 741 824 B
one gigabyte    �1 GB = 10^9 B = 1 000 000 000 B"

So all the drive manufacturers can they are in accord with the IEC units -
and the RAM makers are all giving us a bit extra free...
