Megabytes per Second to Gigabytes per Second (MB/s to GB/s)
1 megabyte per second (MB/s) = 0.001 gigabytes per second (GB/s). 1 GB/s = 1000 MB/s. Example: 15 MB/s = 15 × 0.001 = 0.015 GB/s.

How to Convert Megabyte per Second to Gigabyte per Second
- 1 MB/s = 0.001 GB/s
- 1 GB/s = 1000 MB/s
- Example: convert 15 MB/s to GB/s: 15 MB/s = 15 × 0.001 GB/s = 0.015 GB/s
Formula
GB/s = MB/s ÷ 1000
Derivation from SI units:
- 1 MB/s = 10⁶ B/s = 8 Mbit/s.
- 1 GB/s = 10⁹ B/s = 8 Gbit/s.
- 1 MB/s = 8000000 bps ÷ 8000000000 bps per GB/s = 0.001 GB/s
Both units are defined exactly, so the factor is exact. Megabyte per Second definition: megabyte per second; Gigabyte per Second definition: gigabyte per second.
Worked examples
- A reading of 25 MB/s converts to 0.025 GB/s.
25 MB/s × 0.001 = 0.025 GB/s - A value of 200 MB/s is 0.2 GB/s.
200 MB/s × 0.001 = 0.2 GB/s

Frequently asked questions
How many gigabytes per second are in 1 megabyte per second?
1 MB/s = 0.001 GB/s.
How do I convert megabytes per second to gigabytes per second?
Multiply the value in MB/s by 0.001, or divide it by 1000. For example, 15 MB/s × 0.001 = 0.015 GB/s.
Is the MB/s to GB/s conversion exact?
Yes. Both units are defined exactly, and 1 MB/s is exactly 0.001 GB/s.
