Gigabytes per Second to Megabytes per Second (GB/s to MB/s)
1 gigabyte per second (GB/s) = 1000 megabytes per second (MB/s). 1 MB/s = 0.001 GB/s. Example: 15 GB/s = 15 × 1000 = 15000 MB/s.

How to Convert Gigabyte per Second to Megabyte per Second
- 1 GB/s = 1000 MB/s
- 1 MB/s = 0.001 GB/s
- Example: convert 15 GB/s to MB/s: 15 GB/s = 15 × 1000 MB/s = 15000 MB/s
Formula
MB/s = GB/s × 1000
Derivation from SI units:
- 1 GB/s = 10⁹ B/s = 8 Gbit/s.
- 1 MB/s = 10⁶ B/s = 8 Mbit/s.
- 1 GB/s = 8000000000 bps ÷ 8000000 bps per MB/s = 1000 MB/s
Both units are defined exactly, so the factor is exact. Gigabyte per Second definition: gigabyte per second; Megabyte per Second definition: megabyte per second.
Worked examples
- A reading of 2 GB/s converts to 2000 MB/s.
2 GB/s × 1000 = 2000 MB/s - A value of 7 GB/s is 7000 MB/s.
7 GB/s × 1000 = 7000 MB/s
