How to use it
- Type the value in the gigabits per second box.
- Read the result in terabits 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
Tbps = Gbps × 0.001
Multiply the value in gigabits per second by 0.001 to get terabits per second.
Example
To convert 25 Gbps to terabits per second: 25 × 0.001 = 0.025 Tbps.

About the units
- Gigabit per second
- Equal to exactly 10^9 bits per second, which is 1000 megabits per second.
- Terabit per second
- Equal to exactly 10^12 bits per second, used for undersea cable and data center capacity.
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 terabits per second are in one gigabit per second?
1 Gbps = 0.001 Tbps exactly.
How do I convert gigabits per second to terabits per second?
Use Tbps = Gbps × 0.001. For example, 25 Gbps = 0.025 Tbps.
How many gigabits per second are in one terabit per second?
1 Tbps = 1,000 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.
