No. The big 'K' stands for 1024, 1000 is small 'k'.
The big 'K' was chosen exactly to differ 1024 from 1000 - small 'k'.

But this can't be applied for 'M' because big 'M' is 1 000 000, while smal
'm' is 0.001 (1/1000).

Luckily, HDD manufacturers count with KB/KiB (1024B)'s, so 10GB HDD was
counted as 1 000 000 KB - 1 024 000 000 Bytes. This was because HDD's use
512B sectors, and it's easier to divide number of sectors by 2 than to
multiply it by 512.
