How to use it
- Type the value in the terabytes 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 = TB/s × 1,000
Multiply the value in terabytes per second by 1,000 to get gigabytes per second.
Example
To convert 25 TB/s to gigabytes per second: 25 × 1,000 = 25,000 GB/s.
Conversion table
| Terabytes per second (TB/s) | Gigabytes per second (GB/s) |
|---|---|
| 1 | 1,000 |
| 2 | 2,000 |
| 3 | 3,000 |
| 5 | 5,000 |
| 10 | 10,000 |
| 20 | 20,000 |
| 25 | 25,000 |
| 50 | 50,000 |
| 100 | 100,000 |
| 250 | 250,000 |
| 500 | 500,000 |
| 1,000 | 1,000,000 |
About the units
- Terabyte per second
- Equal to 10^12 bytes per second, which is exactly 8 terabits per second. Seen in graphics card memory bandwidth.
- 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 terabyte per second?
1 TB/s = 1,000 GB/s exactly.
How do I convert terabytes per second to gigabytes per second?
Use GB/s = TB/s × 1,000. For example, 25 TB/s = 25,000 GB/s.
How many terabytes per second are in one gigabyte per second?
1 GB/s = 0.001 TB/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.
