Unit definition
Kilobytes per second (kB/s) One kilobytes per second equals 8,000 bit per second.
Unit history
Kilobytes per second is represented here using its modern SI definition or an internationally accepted relationship to an SI base unit.
Step by step
1. Parse the value, including fractions.
2. Convert kB/s to bit per second.
3. Convert the base value to MB/s and apply your display precision.
Understand the result before using it
Kilobytes per second to Megabytes per second converts a value measured in Kilobytes per second (kB/s) into the equivalent value in Megabytes per second (MB/s). The numerical value changes because the size and definition of the selected unit changes; the underlying quantity does not.
Calculated result
The conversion follows the displayed unit relationship. Display rounding can hide additional digits, and measured inputs cannot become more accurate merely by changing units.
Formula, assumptions, and example
Formula
result = input × 8000 ÷ 8000000
Assumptions
- Kilobytes per second and Megabytes per second represent the same data-transfer speed quantity.
- The input is expressed in kB/s; the output is expressed in MB/s.
- The unit definitions and conventional relationship shown on this page apply.
Worked example
1 kB/s = 0.001 MB/s. For another value, apply the same relationship and round only to the precision your source measurement supports.
When to use it
Good uses
- Read a kB/s measurement in a document that expects MB/s.
- Compare a kilobytes per second value with a value reported in megabytes per second.
- Check the kB/s-to-MB/s arithmetic before copying the result into another calculation.
Limitations
Common mistakes to avoid
- A byte contains eight bits; advertised network speed does not guarantee the same application download rate.
- Round the output to a precision justified by the original measurement.
- Verify safety-critical, regulated, laboratory, and contractual conversions against the controlling standard.

Questions about this calculation
How do I convert Kilobytes per second to Megabytes per second?
result = input × 8000 ÷ 8000000 Using the displayed relationship, 1 kB/s equals 0.001 MB/s.
How many Megabytes per second are in one Kilobytes per second?
One Kilobytes per second is 0.001 Megabytes per second. The displayed digits may be rounded.
Can I reverse the kB/s to MB/s conversion?
Yes. Swap the source and target units in the converter. The reverse relationship converts MB/s back to kB/s.
Is the Kilobytes per second to Megabytes per second result exact?
The conversion follows the displayed unit relationship. Display rounding can hide additional digits, and measured inputs cannot become more accurate merely by changing units.
