Gibibyte (GiB)
A gibibyte is 2³⁰ = 1,073,741,824 bytes, about 7.37 % more than a gigabyte. RAM is built in binary sizes, so “16 GB” of memory is really 16 GiB.
Symbol: GiB
Quantity: amount of digital information
SI relation: 1 GiB = 8589934592 bit (exact)
Derivation: 1 GiB = 2³⁰ bytes = 1,073,741,824 bytes.
Exact: yes, by definition
Typical uses
- RAM capacity
- Virtual machine and cloud instance memory
- Windows drive sizes (shown as GB)
