SI Decimal Prefixes: How TB to Tb Is Calculated
Both terabytes and terabits are SI decimal units, so every prefix step is exactly 1,000 and 1 TB = 8 Tb. This is the convention behind advertised link speeds and drive specifications. Because one unit counts bits and the other bytes, the factor also includes a factor of 8.
| Unit | Standard | Prefix step | 1 unit equals |
|---|---|---|---|
| Terabyte (TB) | SI decimal | 1,000 | 8,000,000,000,000 bits |
| Terabit (Tb) | SI decimal | 1,000 | 1,000,000,000,000 bits |

FAQs: Terabyte to Terabit Conversion
6 questions Quick answers on converting terabytes to terabits, using the same factors as the converter above.
-
How many terabits are in 1 terabyte?
1 TB = 8 Tb
1 Terabyte (TB) equals 8 Terabits using the SI decimal standard.
-
How many terabytes are in 1 terabit?
1 Tb = 0.125 TB
1 Terabit (Tb) equals 0.125 Terabytes.
-
How do I convert terabytes to terabits?
TB × 8 = Tb
Multiply the terabyte value by 8 to get terabits. For example, 10 TB = 80 Tb. To convert back (vice versa), multiply terabits by 0.125.
-
Is a terabyte bigger than a terabit?
TB is 8× larger than Tb
Yes. 1 TB = 8 Tb, so the terabyte is the larger data storage unit.
-
Does TB to Tb use SI decimal or binary prefixes?
Base 10 (SI): 1,000 per step
Both terabytes and terabits are SI decimal (base 10) units, so each prefix step is exactly 1,000, giving 1 TB = 8 Tb. Because one unit counts bits and the other bytes, the factor also includes a factor of 8. The binary (IEC) versions count in base 2 steps of 1,024 instead.
-
What is Terabyte (TB) commonly used for?
Common uses of the terabyte (TB) include: External hard drives, NAS storage, video libraries, enterprise backups.
