Kilobytes per Second to Kilobits per Second (KB/s to kbps)

Type in either box: it converts both ways, accepts sums like 12*3, and shows every other bandwidth unit too.

1 KB/s = 8 kbps in decimal (SI) units, or 8.192 kbps in binary units, the way Windows and RAM count. Use the Decimal / Binary switch below to pick.

How to convert kilobytes per second to kilobits per second

To convert kilobytes per second (KB/s) to kilobits per second (kbps), multiply the value in kilobytes per second by 8.

kbps = KB/s × 8 (decimal)
kbps = KB/s × 8.192 (binary)

Example: 5 KB/s = 40 kbps, or 40.96 kbps 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 KB/s to kbps into the smart calculator, or mix units: 1 KB/s + 1 kbps.

About the units

Kilobyte per second (KB/s)

A unit of bandwidth.

Kilobit per second (kbps)

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 kilobits per second are in a kilobyte per second?

One kilobyte per second (KB/s) equals 8 kilobits per second in decimal (SI) counting, or 8.192 kilobits per second in binary counting (1 KB = 1,024 B), which Windows uses.

How do I convert kilobytes per second to kilobits per second?

To convert kilobytes per second to kilobits per second, multiply the value in kilobytes per second by 8. The formula is kbps = KB/s × 8. For example, 5 KB/s = 40 kbps.

What is 5 KB/s in kbps?

5 kilobytes per second is 40 kilobits per second.

Which is bigger, a kilobyte per second or a kilobit 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.
