Common pitfalls and look-alike units
This page uses SI decimal units: 1 KB = 1000 B. Binary contexts use KiB (1 KiB = 1024 B). Drive makers label in decimal while operating systems often display binary, which is why a 500 GB drive shows about 465 GiB — expected, not a defect.
Frequently asked questions
How many kilobytes are in a megabyte?
1 megabyte (MB) equals 1000 kilobyte (KB).
How do I convert megabytes to kilobytes?
Multiply the megabyte value by 1000 to get kilobyte — for example, 2 megabytes = 2000 kilobyte. Note: this page uses SI decimal units (1 KB = 1000 B). Binary units (KiB/MiB, 1 KiB = 1024 B) give different values.
How do I convert kilobytes back to megabytes?
1 kilobyte equals 0.001 megabyte. Use the swap button or the reverse conversion page linked on this page.
