What this calculator does
This tool converts kilobytes (kB) into megabytes (MB), one of the most common everyday data-size conversions for file sizes, downloads, and data plans.
How the calculation works
Under the binary convention used by most operating systems, 1 megabyte equals 1024 kilobytes. Under the decimal convention often used for data plans and storage marketing, 1 megabyte equals 1000 kilobytes. The calculator divides your kilobyte value by the chosen base to get megabytes, and again to get gigabytes.
This tool is intended for general reference and educational use.
