Strictly speaking the SI units are kB, etc. for 1000 bytes, and IEC
KiB, etc. for 1024 bytes. For memory sizes, it's usually obvious
enough from context which one is meant, so there's not much of a point
to change it. It's more ambiguous for e.g. file or disk sizes where
drive vendors often use 1000 based units, and transfer speeds where
"b" usually means bits.

But as I said, in most cases it's obvious enough from context, and
"KB" instead of "Kb" isn't really much clearer.
