How to convert megabytes to kilobytes

In binary, 1 MiB = 1024 KiB. This distinction matters when comparing storage advertised by manufacturers (decimal) vs what your operating system reports (binary).
1 MB = 1000 KB = 1,000,000 bytes (decimal). This conversion is commonly needed for understanding file sizes, email attachments, and internet speed limits.
