How to use it
- Type the value in the kilobits per second box.
- Read the result in kilobytes per second as you type, and pick the precision you need.
- Swap the direction to convert back, or copy the result.
How it is calculated
kB/s = kbps × 0.125
Multiply the value in kilobits per second by 0.125 to get kilobytes per second.
Example
To convert 25 kbps to kilobytes per second: 25 × 0.125 = 3.125 kB/s.

About the units
- Kilobit per second
- Equal to exactly 1000 bits per second, used for slow connections and audio bitrates.
- Kilobyte per second
- Equal to 1000 bytes per second (decimal kilobyte), which is exactly 8000 bits per second.
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 kilobytes per second are in one kilobit per second?
1 kbps = 0.125 kB/s exactly.
How do I convert kilobits per second to kilobytes per second?
Use kB/s = kbps × 0.125. For example, 25 kbps = 3.125 kB/s.
How many kilobits per second are in one kilobyte per second?
1 kB/s = 8 kbps.
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.
