Formula and reverse conversion
The formula
To convert by hand: MB = KB ÷ 1000. Going back the other way, one MB is 1000 KB.
Decimal and binary units are not the same
Storage is sold in decimal units — a kilobyte is 1000 bytes — while operating systems often count in binary, where a kibibyte is 1024. That is the whole reason a “500 GB” drive shows up as roughly 465 GiB in the system.
MB = KB ÷ 1000
