Megabytes per Second to Bytes per Second (MB/s to B/s)
1 megabyte per second (MB/s) = 1000000 bytes per second (B/s). 1 B/s = 0.000001 MB/s. Example: 15 MB/s = 15 × 1000000 = 15000000 B/s.

How to Convert Megabyte per Second to Byte per Second
- 1 MB/s = 1000000 B/s
- 1 B/s = 0.000001 MB/s
- Example: convert 15 MB/s to B/s: 15 MB/s = 15 × 1000000 B/s = 15000000 B/s
Formula
B/s = MB/s × 1000000
Derivation from SI units:
- 1 MB/s = 10⁶ B/s = 8 Mbit/s.
- 1 B/s = 8 bit/s.
- 1 MB/s = 8000000 bps ÷ 8 bps per B/s = 1000000 B/s
Both units are defined exactly, so the factor is exact. Megabyte per Second definition: megabyte per second; Byte per Second definition: byte per second.
Worked examples
- A reading of 25 MB/s converts to 25000000 B/s.
25 MB/s × 1000000 = 25000000 B/s - A value of 200 MB/s is 200000000 B/s.
200 MB/s × 1000000 = 200000000 B/s

Where it's used
Megabytes per Second are used for download and copy speeds, while bytes per second appear in file transfer speeds. Both measure data transfer rate (bandwidth), so the conversion is a fixed factor.

Frequently asked questions
How many bytes per second are in 1 megabyte per second?
1 MB/s = 1000000 B/s.
How do I convert megabytes per second to bytes per second?
Multiply the value in MB/s by 1000000. For example, 15 MB/s × 1000000 = 15000000 B/s.
Is the MB/s to B/s conversion exact?
Yes. Both units are defined exactly, and 1 MB/s is exactly 1000000 B/s.
