Don't forget the 1.44 MB floppy disk, which has a capacity of 1,474,560 bytes
(1024 x 1000 x 1.44 bytes). That's called a "3.5 inch disk" even though the
standard is a hard metric 90 mm, so the real measurement is 3.543 inches.
And I won't mention the mebibyte or the kibibyte, other than to drop the link,

But note that NIST's examples implicitly accept lowercase "b" as "bit" and
uppercase "B" as "byte."
