- Sorry about this. The sizes of PC floppy disks used by IBM and others are:
-
- 160K 180K 320K 360K 720K 1200K 1440K 2880K
-
- where 1K = 1024 bytes. The reason we see "1.2M, 1.44M, 2.88M" is *not* due
- to confusion, but to IBM's own definition of "megabyte" which is:
-
- 1024K when dealing with internal memory,
- 1000K when dealing with disks.
-
- I have actually seen this "policy" in print, so don't flame me for it.
