Unit definition
Bits per second (bit/s) One bits per second equals 1 bit per second.
Unit history
Bits 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 bit/s to bit per second.
3. Convert the base value to Mb/s and apply your display precision.
Understand the result before using it
Bits per second to Megabits per second converts a value measured in Bits per second (bit/s) into the equivalent value in Megabits 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 × 1 ÷ 1000000
Assumptions
- Bits per second and Megabits per second represent the same data-transfer speed quantity.
- The input is expressed in bit/s; the output is expressed in Mb/s.
- The unit definitions and conventional relationship shown on this page apply.
Worked example
1 bit/s = 0.000001 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 bit/s measurement in a document that expects Mb/s.
- Compare a bits per second value with a value reported in megabits per second.
- Check the bit/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 Bits per second to Megabits per second?
result = input × 1 ÷ 1000000 Using the displayed relationship, 1 bit/s equals 0.000001 Mb/s.
How many Megabits per second are in one Bits per second?
One Bits per second is 0.000001 Megabits per second. The displayed digits may be rounded.
Can I reverse the bit/s to Mb/s conversion?
Yes. Swap the source and target units in the converter. The reverse relationship converts Mb/s back to bit/s.
Is the Bits per second to Megabits 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.
