Unit definition
Gigabits per second (Gb/s) One gigabits per second equals 1,000,000,000 bit per second.
Unit history
Gigabits 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 Gb/s to bit per second.
3. Convert the base value to bit/s and apply your display precision.
Understand the result before using it
Gigabits per second to Bits per second converts a value measured in Gigabits per second (Gb/s) into the equivalent value in Bits per second (bit/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 × 1000000000 ÷ 1
Assumptions
- Gigabits per second and Bits per second represent the same data-transfer speed quantity.
- The input is expressed in Gb/s; the output is expressed in bit/s.
- The unit definitions and conventional relationship shown on this page apply.
Worked example
1 Gb/s = 1,000,000,000 bit/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 Gb/s measurement in a document that expects bit/s.
- Compare a gigabits per second value with a value reported in bits per second.
- Check the Gb/s to bit/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 Gigabits per second to Bits per second?
result = input × 1000000000 ÷ 1. Input is in Gb/s; result is in bit/s. 1 Gb/s = 1,000,000,000 bit/s. The displayed digits may be rounded.
What is 1 Gb/s in bit/s?
1 Gb/s = 1,000,000,000 bit/s. The displayed digits may be rounded.
Can I reverse the Gb/s to bit/s conversion?
Yes. Swap the source and target units in the converter. The reverse relationship converts bit/s back to Gb/s.
Is the Gigabits per second to Bits 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.
