because the sizes are measured in blocks originally, and a block is 1024
bytes, which is one KiB but 1.024 KB.
Sectors are 512 bytes, and blocks (on hard disks) are typically
4096 bytes (but that's determined when you format the partition,
and is determined at run-time).
But I believe the common filesystems use 1024-byte blocks anyway.
At least space measurements seem to be done in blocks.
lthough a few years ago I recall that both 512- and 1024 blocks were in
use -- very confusing.
Block sizes for several common file systems (ext2, ntfs, fat32) use
blocks whose sizes are multiples of 512 or 1024. 4096 is common for a
reasonable sized partitions. Powers of two are fairly obvious from a
hardware point of view.
