Megabits per Second to Gigabytes per Second (Mbps to GB/s)
1 megabit per second (Mbps) = 0.000125 gigabytes per second (GB/s). 1 GB/s = 8000 Mbps. Example: 15 Mbps = 15 × 0.000125 = 0.001875 GB/s.

How to Convert Megabit per Second to Gigabyte per Second
- 1 Mbps = 0.000125 GB/s
- 1 GB/s = 8000 Mbps
- Example: convert 15 Mbps to GB/s: 15 Mbps = 15 × 0.000125 GB/s = 0.001875 GB/s
Formula
GB/s = Mbps ÷ 8000
Derivation from SI units:
- 1 Mbit/s = 10⁶ bit/s.
- 1 GB/s = 10⁹ B/s = 8 Gbit/s.
- 1 Mbps = 1000000 bps ÷ 8000000000 bps per GB/s = 0.000125 GB/s
Both units are defined exactly, so the factor is exact. Megabit per Second definition: megabit per second; Gigabyte per Second definition: gigabyte per second.
Worked examples
- A reading of 25 Mbps converts to 0.003125 GB/s.
25 Mbps × 0.000125 = 0.003125 GB/s - A value of 200 Mbps is 0.025 GB/s.
200 Mbps × 0.000125 = 0.025 GB/s

Frequently asked questions
How many gigabytes per second are in 1 megabit per second?
1 Mbps = 0.000125 GB/s.
How do I convert megabits per second to gigabytes per second?
Multiply the value in Mbps by 0.000125, or divide it by 8000. For example, 15 Mbps × 0.000125 = 0.001875 GB/s.
Is the Mbps to GB/s conversion exact?
Yes. Both units are defined exactly, and 1 Mbps is exactly 0.000125 GB/s.
