Gigabytes per Second to Megabits per Second (GB/s to Mbps)
1 gigabyte per second (GB/s) = 8000 megabits per second (Mbps). 1 Mbps = 0.000125 GB/s. Example: 15 GB/s = 15 × 8000 = 120000 Mbps.

How to Convert Gigabyte per Second to Megabit per Second
- 1 GB/s = 8000 Mbps
- 1 Mbps = 0.000125 GB/s
- Example: convert 15 GB/s to Mbps: 15 GB/s = 15 × 8000 Mbps = 120000 Mbps
Formula
Mbps = GB/s × 8000
Derivation from SI units:
- 1 GB/s = 10⁹ B/s = 8 Gbit/s.
- 1 Mbit/s = 10⁶ bit/s.
- 1 GB/s = 8000000000 bps ÷ 1000000 bps per Mbps = 8000 Mbps
Both units are defined exactly, so the factor is exact. Gigabyte per Second definition: gigabyte per second; Megabit per Second definition: megabit per second.
Worked examples
- A reading of 2 GB/s converts to 16000 Mbps.
2 GB/s × 8000 = 16000 Mbps - A value of 7 GB/s is 56000 Mbps.
7 GB/s × 8000 = 56000 Mbps
