How to use it
- Type the value in the gigabits per second box.
- Read the result in gigabytes 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
GB/s = Gbps × 0.125
Multiply the value in gigabits per second by 0.125 to get gigabytes per second.
Example
To convert 25 Gbps to gigabytes per second: 25 × 0.125 = 3.125 GB/s.

About the units
- Gigabit per second
- Equal to exactly 10^9 bits per second, which is 1000 megabits per second.
- Gigabyte per second
- Equal to 10^9 bytes per second (decimal gigabyte), which is exactly 8 gigabits per second. Used for SSD speeds.
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 gigabytes per second are in one gigabit per second?
1 Gbps = 0.125 GB/s exactly.
How do I convert gigabits per second to gigabytes per second?
Use GB/s = Gbps × 0.125. For example, 25 Gbps = 3.125 GB/s.
How many gigabits per second are in one gigabyte per second?
1 GB/s = 8 Gbps.
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.
