Mebibytes (MiB) to Kibibytes (KiB) Conversion
Mebibytes
The mebibyte (MiB) is a unit of digital information equal to exactly 1,048,576 bytes (2²⁰ bytes). Operating systems such as Linux and modern versions of Windows and macOS use mebibytes when reporting RAM usage and file sizes, though they sometimes still display the label "MB." A standard 1.44 MB floppy disk actually contained 1,474,560 bytes — not 1,440,000 — making it correctly described as 1.41 MiB.
Kibibytes
The kibibyte (KiB) is a unit of digital information equal to exactly 1,024 bytes (2¹⁰ bytes), defined by IEC 80000-13. It is the precise binary equivalent of what operating systems have historically called a "kilobyte." Memory chip capacities, CPU cache sizes, and file system block sizes are exactly described in kibibytes, while hard drive manufacturers use the decimal kilobyte (1,000 bytes) — the root cause of the persistent storage capacity discrepancy.
