Did you know that that Kibi, Mebi, Gibi, Tebi, Pebi, Exbi, Zebi, and Yobi binary prefixes have been adopted by IEC, IEEE as well as some other standards organizations?
Although they are not in wide use (yet), they must be considered standardized units. Just because not everyone in the world uses inches, feet, yards and miles doesn't mean that they are not standardized units - they are just not the only standardized units!
I rarely use these binary prefixes myself, but after endless debates and posts about how much is a Gigabyte, and why can I only fit 4.38 GByte on my DVD when the packaging clearly states 4.7 GB, I'm coming around to thinking that maybe we should use the binary prefixes and units explicitly - e.g. the capacity of a DVD is 4.38 GiB.
