Convert Bits per Second to Bytes per Second (bps to B/s)
1 bit per second (bps) = 0.125 bytes per second (B/s). 1 B/s = 8 bps. Example: 15 bps = 15 × 0.125 = 1.875 B/s.

How to Convert Bit per Second to Byte per Second
- 1 bps = 0.125 B/s
- 1 B/s = 8 bps
- Example: convert 15 bps to B/s: 15 bps = 15 × 0.125 B/s = 1.875 B/s
Formula
B/s = bps ÷ 8
Derivation from SI units:
- One bit transferred each second.
- 1 B/s = 8 bit/s.
Both units are defined exactly, so the factor is exact. Bit per Second definition: bit per second; Byte per Second definition: byte per second.
Worked examples
- A reading of 9600 bps converts to 1200 B/s.
9600 bps × 0.125 = 1200 B/s - A value of 115200 bps is 14400 B/s.
115200 bps × 0.125 = 14400 B/s

Where it's used
Bits per Second are used for serial ports and modems (baud-like rates), 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 bit per second?
1 bps = 0.125 B/s.
How do I convert bits per second to bytes per second?
Multiply the value in bps by 0.125, or divide it by 8. For example, 15 bps × 0.125 = 1.875 B/s.
Is the bps to B/s conversion exact?
Yes. Both units are defined exactly, and 1 bps is exactly 0.125 B/s.
