That's the stupidest thing I've ever heard! I'm reverting to Imperial units.
Ever hear of a kibibyte
? I think it's some kind of dog food...
When I first heard that "1 megabyte is now 1,000 KB", and a KB is 1024 bytes, I was thinking, "What, 10^3 * 2^8?".
I later learned that all the prefixes were cleaned up; MB is 1000 KB and 10^3 * 10^3.
And, me_BI_bytes is 2^3 * ki_BI_bytes, or 2^3 * 2^3 bytes.
But that linked article had me stumped on this one:
And if two definitions of the megabyte are not enough, a third megabyte of 1 024 000 bytes is the megabyte used to format the familiar 90 mm (3 1/2 inch), "1.44 MB" diskette. The confusion is real, as is the potential for incompatibility in standards and in implemented systems.
Seriously, the 1.44 MB diskettes didn't even stay consistent within themselves??? SHEESH. Yes, that's 10^3 * 2^8 for you.
Some designers of local area networks have used megabit per second to mean 1 048 576 bit/s, but all telecommunications engineers use it to mean 10^6 bit/s.
When I first heard of the whole Megabyte / Mebibyte issue, I thought it was only hard drive makers trying to pretend that their drives were bigger than their competition. It never occurred to me until now that there was a serious cross-confusion between digital fields and binary fields -- computer networks and telephone networks are now the same.
So, yea, I still mess up sometimes and fail to use the "prefix_BI" form because the straight greek (greek? latin? sumarian?) prefixes are so entrenched in my neural pathways.
