a kilobyte is 2^10 bytes
you're converting 1 megabyte to kilobyte.

short answer: divide 1 megabyte by 2^10.
2^20 / 2^10 = 2^10 kilobyte

long answer: converting units that you learned in science class
(1 megabyte / 1) * (2^20 bytes / 1 megabyte) * (1 kilobyte / 2^10 bytes)

megabyte and bytes cancels out and you're left with
2^20 kilobyte / 2^10 = 2^10 kilobyte
