How to Convert Manually
Use these steps to convert Kilobyte per Second values to Byte per Second without the calculator.
- Write down the value in Kilobyte per Second (KB-s) that you want to convert.
- Multiply that value by 1000.
- For example, 10 Kilobyte per Second × 1000 = 10000 Byte per Second.
- Label the result as Byte per Second (B-s).

About Kilobyte per Second and Byte per Second
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. 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. One Kilobyte per Second equals 1000 Byte per Second (1 KB-s = 1000 B-s). Kilobyte per Second is used in file manager copy and move operations and in FTP and SFTP transfer speed readouts. Byte per Second is used in file download progress (browsers, torrent clients).
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).
