MB to KB Converter

Convert megabytes (MB) to kilobytes (KB). 1 MB = 1,000 KB.

How to convert MB to KB

Megabytes and kilobytes are both decimal (power-of-1000) units defined by the SI standard. One MB is 1,000,000 bytes and one KB is 1,000 bytes, so multiply a MB value by 1,000 to get KB.

KB vs KiB: 1000 or 1024?

SI units (KB, MB, GB, TB) are powers of 1000. Binary units (KiB, MiB, GiB, TiB) are powers of 1024. Storage manufacturers advertise in decimal units while operating systems often report binary units, which is why drives appear "smaller" than advertised. When precision matters, name the unit explicitly.
