Right.
8 Bit = 1 Byte 1024 Byte = 1 KB 1024 KB = 1 MB 1024 MB ...
So we are talking about that, beacuse the X-Byte is defined as 1024 and not as 1000 of the previous step.

What _you_ mean can not be determied from me. But *I* would mean 1.048.574, otherwise I would say the 9xxx number or say nearly 1 MB.

That's the sense of them.
