Gigabytes per Second to Gigabits per Second (GB/s to Gbps)
1 gigabyte per second (GB/s) = 8 gigabits per second (Gbps). 1 Gbps = 0.125 GB/s. Example: 15 GB/s = 15 × 8 = 120 Gbps.

How to Convert Gigabyte per Second to Gigabit per Second
- 1 GB/s = 8 Gbps
- 1 Gbps = 0.125 GB/s
- Example: convert 15 GB/s to Gbps: 15 GB/s = 15 × 8 Gbps = 120 Gbps
Formula
Gbps = GB/s × 8
Derivation from SI units:
- 1 GB/s = 10⁹ B/s = 8 Gbit/s.
- 1 Gbit/s = 10⁹ bit/s.
- 1 GB/s = 8000000000 bps ÷ 1000000000 bps per Gbps = 8 Gbps
Both units are defined exactly, so the factor is exact. Gigabyte per Second definition: gigabyte per second; Gigabit per Second definition: gigabit per second.
Worked examples
- A reading of 2 GB/s converts to 16 Gbps.
2 GB/s × 8 = 16 Gbps - A value of 7 GB/s is 56 Gbps.
7 GB/s × 8 = 56 Gbps
