How to convert kilobits per second to kilobytes per second
To convert kilobits per second (kbps) to kilobytes per second (KB/s), multiply the value in kilobits per second by 0.125.
KB/s = kbps × 0.125 (decimal)
KB/s = kbps × 0.1220703125 (binary)
Example: 5 kbps = 0.625 KB/s, or 0.6103515625 KB/s in binary.
Decimal (SI) counting steps by 1,000 and is what drive makers, macOS and phones use. Binary counting steps by 1,024 and is what Windows and RAM use; its unambiguous IEC names are KiB, MiB and GiB. Bits are decimal either way.
You can also type 5 kbps to KB/s into the smart calculator, or mix units: 1 kbps + 1 KB/s.

About the units
Kilobit per second (kbps)
A unit of bandwidth.
Kilobyte per second (KB/s)
A unit of bandwidth.
Network speeds are sold in bits per second, which are always decimal (1 Mbps = 1,000 kbps). Download dialogs show bytes per second, which some apps count in decimal (1 MB/s = 1,000 KB/s) and others in binary (1 MB/s = 1,024 KB/s). Because a byte is 8 bits, a 100 Mbps connection tops out around 12.5 MB/s (11.9 binary MB/s) before protocol overhead.
Questions and answers
How many kilobytes per second are in a kilobit per second?
One kilobit per second (kbps) equals 0.125 kilobytes per second in decimal (SI) counting, or 0.1220703125 kilobytes per second in binary counting (1 KB = 1,024 B), which Windows uses.
How do I convert kilobits per second to kilobytes per second?
To convert kilobits per second to kilobytes per second, multiply the value in kilobits per second by 0.125. The formula is KB/s = kbps × 0.125. For example, 5 kbps = 0.625 KB/s.
What is 5 kbps in KB/s?
5 kilobits per second is 0.625 kilobytes per second.
Which is bigger, a kilobit per second or a kilobyte per second?
A kilobyte per second is bigger: 1 KB/s = 8 kbps.
Why is my download speed lower than my internet plan?
Plans are sold in megabits per second (Mbps) and downloads show megabytes per second (MB/s). A byte is 8 bits, so 100 Mbps is at most 12.5 MB/s, or 11.92 MB/s if your download manager counts in binary, and protocol overhead takes a little more.
Is 1 MB/s 1,000 KB/s or 1,024 KB/s?
It depends on the app. Decimal counting gives 1 MB/s = 1,000 KB/s; binary counting (common in Windows tools and some download managers) gives 1,024 KB/s. Use the Decimal / Binary switch to match your app. Bit rates like Mbps are always decimal.
