How to Convert Terabytes to Tebibytes
To convert terabytes (decimal/SI) to tebibytes (binary/IEC), multiply by 0.909494701773. Decimal units use base 1,000, while binary units use base 1,024. Try the TiB to TB calculator.
TB is a decimal (SI) unit—what storage manufacturers advertise. 1 TB = 1,000 of the smaller unit. Use our convert TB to EB.
TiB is a binary (IEC) unit—what operating systems often display. 1 TiB = 1,024 of the smaller unit. You might also need: Pb → TiB.
1 TB = 0.909494701773 TiB (using SI decimal standard) — or equivalently, 1 TiB = 1.0995116278TB.
TB to TiB Conversion Formula
// Convert TB to TiB
TiB = TB × 0.909494701773
// Reverse: Convert TiB to TB
TB = TiB × 1.0995116278Terabyte to Tebibyte Conversion Examples

What Is a Terabyte (TB)? Definition and Uses
A terabyte is 1,000 gigabytes or 1,000,000,000,000 bytes. Common size for modern hard drives and SSDs. Use our Gibibits to Yobibytes.
The terabyte is a SI decimal unit of digital information storage. It uses base 1,000 following the SI (International System of Units) standard. Use our Gibibytes Per Second to Pebibits Per Second converter.
Common uses: External hard drives, NAS storage, video libraries, enterprise backups Check out our Terabytes to Gigabits calculator.
1 TB = 8 × 10¹² bits = 1 × 10¹² bytes.
The terabyte can be abbreviated as TB; for example, 1 terabyte can be written as 1 TB.
What Is a Tebibyte (TiB)? Definition and Uses
A tebibyte is 1,024 gibibytes or 1,099,511,627,776 bytes. The actual usable capacity shown by operating systems. You might also need: convert Gigabits to Tebibytes.
The tebibyte is a IEC binary unit of digital information storage. It uses base 1,024 following the IEC (International Electrotechnical Commission) standard. Use our Pebibytes to Exabytes conversion.
Common uses: OS-reported drive capacity, NAS actual storage, enterprise storage systems Related: Kbps to Megabytes Per Second converter.
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.

SI Decimal vs Binary: Why Two Different Standards?
When converting terabytes to tebibytes, 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.
