How to Convert Tebibytes to Gigabytes
To convert tebibytes (binary/IEC) to gigabytes (decimal/SI), multiply by 1,099.511628. Binary units use base 1,024, while decimal units use base 1,000—this creates small differences that accumulate at larger scales. Check out our GB to TiB calculator.
TiB is a binary (IEC) unit where 1 TiB = 1,024 of the smaller unit. Operating systems like Windows typically display storage using binary calculations. Use our convert TiB to Zib.
GB is a decimal (SI) unit where 1 GB = 1,000 of the smaller unit. Storage manufacturers use decimal units, which is why a "1 TB" drive shows less in Windows. Learn more: nibble → GB.
1 TiB = 1,099.511628 GB (using SI decimal standard) — which means there are 1,099.511628gigabytes in every tebibyte.
TiB to GB Conversion Formula
// Convert TiB to GB
GB = TiB × 1,099.511628
// Reverse: Convert GB to TiB
TiB = GB × 0.000909494702

What Is a Tebibyte?
A tebibyte is 1,024 gibibytes or 1,099,511,627,776 bytes. The actual usable capacity shown by operating systems. Related: Megabytes to Terabytes.
The tebibyte is a IEC binary unit of digital information storage. It uses base 1,024 following the IEC (International Electrotechnical Commission) standard. Related: Tebibytes Per Second to Gibibits Per Second converter.
Common uses: OS-reported drive capacity, NAS actual storage, enterprise storage systems Check out our Tebibytes to Bytes calculator.
1 TiB = 9 × 10¹² bits = 1 × 10¹² bytes.
The tebibyte can be abbreviated as TiB; for example, 1 tebibyte can be written as 1 TiB.
What Is a Gigabyte?
A gigabyte is 1,000 megabytes or 1,000,000,000 bytes using the SI decimal standard. This is what hard drive manufacturers typically use. Learn more: convert Bytes to Gigabytes.

SI Decimal vs Binary: Why Two Different Standards?
When converting tebibytes to gigabytes, different tools may give slightly different results. This is because there are two competing standards for measuring digital storage:
| Standard | Base | 1 KB equals | Used By |
|---|---|---|---|
| SI Decimal | 1000 | 1,000 bytes | Hard drive manufacturers, macOS, network speeds |
| Binary (IEC) | 1024 | 1,024 bytes | Windows, Linux (partially), RAM specifications |
Note: Our calculator defaults to SI decimal (base 1000) to match the box label. To match Windows, toggle the standard at the top of the calculator.
