How to Convert Manually
Use these steps to convert Byte per Second values to Kilobyte per Second without the calculator.
- Write down the value in Byte per Second (B-s) that you want to convert.
- Multiply that value by 0.001.
- For example, 10 Byte per Second × 0.001 = 0.01 Kilobyte per Second.
- Label the result as Kilobyte per Second (KB-s).

About Byte per Second and Kilobyte per Second
The byte per second (B/s) equals 8 bits per second. It is commonly used in file transfer progress indicators and storage benchmarks where download or copy speed is expressed in bytes rather than bits. The kilobyte per second (KB/s) equals 8,000 bits per second (8 Kbps). It appears in file manager copy speed readouts and FTP transfer statistics. One Byte per Second equals 0.001 Kilobyte per Second (1 B-s = 0.001 KB-s). Byte per Second is used in file download progress (browsers, torrent clients) and in storage copy speed in operating systems. Kilobyte per Second is used in file manager copy and move operations.
Precision and Rounding:Data transfer rates are almost always quoted in SI decimal prefixes (1 Kbps = 1,000 bps), not binary (1 Kibps = 1,024 bps). Internet service providers universally use SI prefixes. When converting to bytes per second, remember 1 byte = 8 bits exactly. Never round this factor.
See our guide to megabits vs. megabytes if you're unsure which one your download speed is quoted in.
Conversion factors per NIST Special Publication 811 and the BIPM SI Brochure (9th edition) (reference).
