GiB to Bytes Converter
Convert gibibytes to bytes — 1,073,741,824 bytes to the gibibyte. Results update as you type; exact factors shown.
One gibibyte (2³⁰) is 1,073,741,824 bytes — see the exact factor, not a rounded rule of thumb.
How the gib to bytes converter works
Storage converts through the byte (8 bits). Drive makers and network speeds use decimal prefixes (1 GB = 10⁹ bytes); operating systems often report binary units (1 GiB = 2³⁰ = 1,073,741,824 bytes) — sometimes labelled "GB". The gap is 7.4% at the gigabyte and 10% at the terabyte.
The UK is metric for most trade and science but keeps miles, pints, stone and mpg (with the imperial gallon) in daily life.

FAQFrequently asked questions about data conversion
How many bytes in a gibibyte?
Exactly 1,073,741,824 — two to the thirtieth.
How does that compare to a gigabyte?
A gigabyte is 1,000,000,000 bytes, 7.4% less.
Why does 16 GB of RAM show as 16 GB?
Because memory really is sold in binary units. It is storage that is sold decimal and reported binary.
What is 8 GiB?
8,589,934,592 bytes.
When did the prefixes arrive?
IEC standardised kibi, mebi, gibi and tebi in 1998.
