Bytes to GiB Converter
Convert bytes to gibibytes — divide by 1,073,741,824. Results update as you type; exact factors shown.
One byte is 9.3132e-10 gibibyte (2³⁰) — see the exact factor, not a rounded rule of thumb.
How the bytes to gib 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?
1,073,741,824.
Why does my 1 TB drive show 931 GB?
Because the operating system reports 931 gibibytes and labels them GB. The drive holds a full decimal terabyte.
What is 1,000,000,000 bytes?
One gigabyte, which is 0.931 GiB.
Is anyone wrong?
No. Storage makers use SI prefixes correctly; operating systems use binary sizes with decimal names.
What is 4 TB in GiB?
3,725 GiB.
