I automatically assume that people that use KB=1000B want to sell me something (and provide less than promised), so should be aggressively ignored or removed from vicinities KB is 1024 bytes, and don't you dare try stealing those 24 bytes from me
Earlier quoted context omitted.
I have no idea what that is supposed to have to do with anything.
It means that is fine for Kilo to mean 1024 in the context of computers and 1000 in the context of distances, because you're never going to be in a situation where that is ambiguous.
E.g. Macs measure file sizes in powers of 10 and call them KB, MB, GB. Windows measures file sizes in powers of 2 and calls them KB, MB, GB instead of KiB, MiB, GiB. Advertised hard drives come in powers of 10. Advertised memory chips come in powers of 2.
When you've got a large amount of data or are allocating an amount of space, are you measuring its size in memory or on disk? On a Mac or on Windows?
A mile is exactly 1000 paces, or 4000 feet. You may disagree, but consider: the word mile come from latin for "one thousand". Therefore a mile must be 1000 of something, namely paces. I hope you find this argument convincing.
I'm sticking with power-of-2 sizes. Invent a new word for decimal, metric units where appropriate. I proposed[0] "kitribytes", "metribytes", "gitribytes", etc. Just because "kilo" has a meaning in one context doesn't mean we're stuck with it in others. It's not as though the ancient Greeks originally meant "kilo" to mean "exactly 1,000". "Giga" just meant "giant". "Tera" is just "monster". SI doesn't have sole owners…
> I'm a big fan of binary numbers, but I have to admit that this convention flouts the widely accepted international standards for scientific prefixes.
He also calls it “an important issue” and had written “1000 MB = 1 gigabyte (GB), 1000 GB = 1 terabyte (TB), 1000 TB = 1 petabyte (PB), 1000 PB = 1 exabyte (EB), 1000 EB = 1 zettabyte (ZB), 1000 ZB = 1 yottabyte (YB)” in his MMIX book even before the new binary prefixes became an international standard.
He is merely complaining that the new names for the binary prefixes sound funny (and has his own proposal like “large megabyte” and notation MMB etc), but he's still using the kilo/mega/etc prefixes with decimal meanings.
Whenever this discussion comes up I liked to point out that even in the computer industry, prefixes like kilo/mega/etc more often mean a power of 10 than a power of 2: I gave some examples in my post https://blog.zorinaq.com/decimal-prefixes-are-more-common-th...
The misuse of those prefixes as powers of 1024, while useful as shorthand for computer memory where binary addressing means, is still exactly that: a misuse of SI prefixes.
There's now a separate set of base-2 prefixes to solve this, and people need to update their language accordingly.

Storage capacity also uses binary prefixes. The distinction here isn't that file sizes are reported in binary numbers and storage capacity is reported in decimal numbers. It's that software uses binary numbers and hard drive manufacturers use decimal numbers. You don't see df reporting files in binary units and capacities in decimal units.
Of that large list of measurements, only bandwidth is measured in bytes, making the argument mostly an exercise in sophistry. You can't convince anyone that KB means 1000 bytes by arguing that kHz means 1000 Hz.
And a megabyte is depending on the context precisely 1000x1000=1,000,000 or 1024x1024=1,048,576 bytes*, except when you're talking about the classic 3.5 inch floppy disks, where "1.44 MB" stands for 1440x1024 bytes, or about 1.47 true MB or 1.41 MiB. * Yeah, I read the article. Regardless of the IEC's noble attempt, in all my years of working with people and computers I've never heard anyone actually pronounce MiB (o…
Well the 1.44 MB, was called that because it was 1440 KB, twice the capacity of the 720k floppy, and 4x the 360k floppy. It made perfect sense to me at that time.
Sectors per track or tracks per side is subject to change. Moreover a different filesystem may have non-linear growth of the MFT/superblock that'll have a different overhead.
