How to use it
- Type the value in the gigabytes per second box.
- Read the result in terabytes 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
TB/s = GB/s × 0.001
Multiply the value in gigabytes per second by 0.001 to get terabytes per second.
Example
To convert 25 GB/s to terabytes per second: 25 × 0.001 = 0.025 TB/s.

About the units
- Gigabyte per second
- Equal to 10^9 bytes per second (decimal gigabyte), which is exactly 8 gigabits per second. Used for SSD speeds.
- Terabyte per second
- Equal to 10^12 bytes per second, which is exactly 8 terabits per second. Seen in graphics card memory bandwidth.
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 terabytes per second are in one gigabyte per second?
1 GB/s = 0.001 TB/s exactly.
How do I convert gigabytes per second to terabytes per second?
Use TB/s = GB/s × 0.001. For example, 25 GB/s = 0.025 TB/s.
How many gigabytes per second are in one terabyte per second?
1 TB/s = 1,000 GB/s.
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.
