Question
How many kilobytes are in a megabyte?
On Koverts’ converter, 1 megabyte (MB) equals 1024 kilobytes (KB).
1 MB (Koverts)
1024 KB
1 MB (SI)
1000 KB
1 KB (Koverts)
1024 bytes
Explanation
Binary file-size math uses 1024: 1 MB = 1024 KB = 1,048,576 bytes.
Some networking docs use SI decimal megabytes where 1 MB = 1000 KB.
When a log says “MB” without context, check whether the tool is binary or decimal.
Important caveat
RAM and OS tools often report mebibyte-style sizes even when they label them “MB”.
