Storage manufacturers and operating systems have historically disagreed on what a 'megabyte' means — this is why a '500 GB' hard drive often shows up as roughly 465 GB in your file explorer.
A kilobyte is technically ambiguous — 1,000 bytes (decimal, used by storage manufacturers) or 1,024 bytes (binary, used by most operating systems) — which is exactly why kibibytes were introduced as an unambiguous alternative.
