What is 1 gibibyte in bytes?
1 gibibyte is equal to exactly 1,073,741,824 bytes.
1 × 1,073,741,824 = 1,073,741,824 bytes
1 gibibyte = 1,073,741,824 bytes
Gibibytes to Bytes formula
B = GiB × 1,073,741,824
The gibibytes to bytes conversion factor is 1,073,741,824, which is exact by definition. 1 gibibyte = 1,073,741,824 bytes, and 1 byte = 9.313225746 × 10⁻¹⁰ gibibytes.
Regional note. Decimal (SI) units count in powers of 1,000 while binary (IEC) units count in powers of 1,024. This is why a drive sold as 1 TB is reported by most operating systems as about 931 GiB.
Worked examples
- 2 gibibytes = 2,147,483,648 bytes — 2 × 1,073,741,824 = 2,147,483,648 bytes

When you need to convert gibibytes to bytes
- Checking whether a file fits inside a storage or upload limit.
- Working out how much of a mobile data allowance a download will use.
- Reconciling the capacity printed on a drive with the smaller figure the operating system reports.
Common mistakes to avoid
- Dividing when you should multiply. Because 1 gibibyte = 1,073,741,824 bytes, the answer should be larger than the number you started with.
- Treating 1 kB as 1,024 bytes. Storage and network figures use decimal units of 1,000; operating systems usually report binary units of 1,024, which is why a 1 TB drive shows as about 931 GiB.
- Rounding too early. Convert first at full precision, then round the final answer to the precision the task actually needs.
How precise does the answer need to be?
Round to two decimals for human-readable sizes. When you are checking a hard limit, use the exact figure: a file 0.4% over an upload cap still fails.
How these units are defined
- Gibibyte (GiB): 1,024 mebibytes — what operating systems often display as 'GB'. This unit's relationship to the SI base unit is exact by definition, so no rounding enters the conversion factor.
- Byte (B): Eight bits. This unit's relationship to the SI base unit is exact by definition, so no rounding enters the conversion factor.
