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.
Australia is fully metric under the National Measurement Act 1960; imperial units appear only in trade with the US and in older documents.

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.
