Mebibytes (MiB) to Gibibytes (GiB) 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.
Gibibytes
The gibibyte (GiB) is a unit of digital information equal to exactly 1,073,741,824 bytes (2³⁰ bytes). It is what operating systems actually measure when reporting hard drive and SSD capacity — a "1 TB" drive (10¹² bytes) appears as approximately 931 GiB in Windows because the OS reports in binary multiples while the manufacturer uses decimal. RAM is always manufactured in exact powers of 2, so a "4 GB" RAM module contains exactly 4 GiB.
