Gibibytes (GiB) to Mebibits (Mibit) Conversion

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.

Mebibits

The mebibit (Mibit) is a unit of digital information equal to exactly 1,048,576 bits (2²⁰ bits). It appears in network engineering and telecommunications when precise binary counts of bits are required — for example, in specifications for wireless protocols and radio channel bandwidth. Like all IEC binary prefix units, it was introduced to provide unambiguous terminology distinct from the decimal megabit (1,000,000 bits).
