How to use it

  1. Type the value in the gigabytes per second box.
  2. Read the result in terabytes per second as you type, and pick the precision you need.
  3. 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.
