How to use it

  1. Type the value in the kilobytes per second box.
  2. Read the result in kilobits per second as you type, and pick the precision you need.
  3. Swap the direction to convert back, or copy the result.

How it is calculated

kbps = kB/s × 8

Multiply the value in kilobytes per second by 8 to get kilobits per second.

Example

To convert 25 kB/s to kilobits per second: 25 × 8 = 200 kbps.

About the units

Kilobyte per second
Equal to 1000 bytes per second (decimal kilobyte), which is exactly 8000 bits per second.
Kilobit per second
Equal to exactly 1000 bits per second, used for slow connections and audio bitrates.

Limits and caveats

  • Results are rounded for display and computed with the browser's floating point precision (about 15 significant digits).
  • Both unit factors are exact by their official definitions.

Questions about this tool

How many kilobits per second are in one kilobyte per second?

1 kB/s = 8 kbps exactly.

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

Use kbps = kB/s × 8. For example, 25 kB/s = 200 kbps.

How many kilobytes per second are in one kilobit per second?

1 kbps = 0.125 kB/s.

Why is my download slower than my plan speed?

Plans are sold in megabits per second while download tools show megabytes per second, so divide by 8: a 100 Mbps plan tops out at 12.5 MB/s in theory. Network protocol overhead takes a little more.

How long does a 1 GB file take at 100 Mbps?

1 GB is 8000 megabits, and 8000 ÷ 100 = 80 seconds under ideal conditions. Real transfers are usually a little slower.
