    FAQ

    How many kilobytes make up one megabyte?

    One megabyte holds 1024 kilobytes, or 1 048 576 bytes, on the binary scale this converter uses. The decimal convention of the SI puts 1000 KB in a megabyte instead, and the IEC name for the 1024-based unit is the mebibyte (MiB).

    What is the formula to convert megabytes to kilobytes?

    Multiply the megabyte value by 1024: 1 MB = 1024 KB, 0.5 MB = 512 KB and 25 MB = 25 600 KB. Dividing by 1024 takes kilobytes back to megabytes.

    Why are attachment limits quoted in MB but image sizes in KB?

    Because the two units are a factor of 1024 apart, and each one fits the size it describes. A 25 MB mail limit is 25 600 KB, while a compressed photo usually weighs 100–500 KB — so somewhere between 50 and 250 of them fit into one message.
