Gigabytes per Second to Terabits per Second (GB/s to Tbps)
1 gigabyte per second (GB/s) = 0.008 terabits per second (Tbps). 1 Tbps = 125 GB/s. Example: 15 GB/s = 15 × 0.008 = 0.12 Tbps.

How to Convert Gigabyte per Second to Terabit per Second
- 1 GB/s = 0.008 Tbps
- 1 Tbps = 125 GB/s
- Example: convert 15 GB/s to Tbps: 15 GB/s = 15 × 0.008 Tbps = 0.12 Tbps
Formula
Tbps = GB/s ÷ 125
Derivation from SI units:
- 1 GB/s = 10⁹ B/s = 8 Gbit/s.
- 1 Tbit/s = 10¹² bit/s.
- 1 GB/s = 8000000000 bps ÷ 1000000000000 bps per Tbps = 0.008 Tbps
Both units are defined exactly, so the factor is exact. Gigabyte per Second definition: gigabyte per second; Terabit per Second definition: terabit per second.
Worked examples
- A reading of 2 GB/s converts to 0.016 Tbps.
2 GB/s × 0.008 = 0.016 Tbps - A value of 7 GB/s is 0.056 Tbps.
7 GB/s × 0.008 = 0.056 Tbps

Frequently asked questions
How many terabits per second are in 1 gigabyte per second?
1 GB/s = 0.008 Tbps.
How do I convert gigabytes per second to terabits per second?
Multiply the value in GB/s by 0.008, or divide it by 125. For example, 15 GB/s × 0.008 = 0.12 Tbps.
Is the GB/s to Tbps conversion exact?
Yes. Both units are defined exactly, and 1 GB/s is exactly 0.008 Tbps.
