KB to MB Converter (Kilobytes to Megabytes)

Your details

Operating systems (Windows, macOS, Linux) use 1,024. Hard-drive and flash manufacturers use 1,000, which is why a drive labelled "256 GB" appears smaller in your OS.

1,024 KB = 1 MB (binary).

  • The result falls in the 1-50 MB range, typical of a high-resolution photo, a short MP3, or a lightweight application.
  • Using the binary standard: 1 MB = 1,024 KB.
  • In raw bytes that is 1,048,576 B.
  • Operating systems display file sizes using the binary standard, while storage device manufacturers use the SI decimal standard, which is why a "500 GB" drive shows as roughly 465 GB in your file explorer.

Next stepIf you are comparing a file size reported by your OS with a storage device label, switch between the binary and SI standards to see the difference.
