Processing and privacy: The result is calculated inside your browser and your data is not sent to any server.

How to use it

  1. Type the value in the megabits per second box.
  2. Read the result in kilobytes 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

kB/s = Mbps × 125

Multiply the value in megabits per second by 125 to get kilobytes per second.

Example

To convert 25 Mbps to kilobytes per second: 25 × 125 = 3,125 kB/s.

About the units

Megabit per second
Equal to exactly 10^6 bits per second, the usual unit in internet and fiber plan adverts.
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 megabit per second?

1 Mbps = 125 kB/s exactly.

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

Use kB/s = Mbps × 125. For example, 25 Mbps = 3,125 kB/s.

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

1 kB/s = 0.008 Mbps.

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.
