Convert Terabytes to Gigabits (TB to Gbit)
1 terabyte (TB) = 8000 gigabits (Gbit). 1 Gbit = 0.000125 TB. Example: 15 TB = 15 × 8000 = 120000 Gbit.

How to Convert Terabyte to Gigabit
- 1 TB = 8000 Gbit
- 1 Gbit = 0.000125 TB
- Example: convert 15 TB to Gbit: 15 TB = 15 × 8000 Gbit = 120000 Gbit
Formula
Gbit = TB × 8000
Derivation from SI units:
- 1 TB = 10¹² bytes = 1000 GB.
- 1 Gbit = 10⁹ bits.
- 1 TB = 8000000000000 bit ÷ 1000000000 bit per Gbit = 8000 Gbit
Both units are defined exactly, so the factor is exact. Terabyte definition: terabyte; Gigabit definition: gigabit.
Worked examples
- A reading of 4 TB converts to 32000 Gbit.
4 TB × 8000 = 32000 Gbit - A value of 12 TB is 96000 Gbit.
12 TB × 8000 = 96000 Gbit
