How to Convert Manually
Use these steps to convert Gigabit per Second values to Terabit per Second without the calculator.
- Write down the value in Gigabit per Second (Gbps) that you want to convert.
- Multiply that value by 0.001.
- For example, 10 Gigabit per Second × 0.001 = 0.01 Terabit per Second.
- Label the result as Terabit per Second (Tbps).

About Gigabit per Second and Terabit per Second
The gigabit per second (Gbps) equals 1,000,000,000 bits per second (10⁹ bps). It is the standard for fibre-optic internet, data-centre interconnects, and NVMe storage throughput. The terabit per second (Tbps) equals 10¹² bits per second. It is used for backbone fibre-optic cable capacity and inter-data-centre links. Single optical fibres can now carry over 10 Tbps using wavelength-division multiplexing. One Gigabit per Second equals 0.001 Terabit per Second (1 Gbps = 0.001 Tbps). Gigabit per Second to Terabit per Second conversion comes up most often in Gigabit and multi-gigabit fibre broadband (1–10 Gbps) and in data-centre server NICs and switches, typically when figures need restating for submarine and intercontinental fibre-optic cables.
Precision and Rounding: Data transfer rates are almost always quoted in SI decimal prefixes (1 Kbps = 1,000 bps), not binary (1 Kibps = 1,024 bps). Internet service providers universally use SI prefixes. When converting to bytes per second, remember 1 byte = 8 bits exactly — never round this factor.
Conversion factors per NIST Special Publication 811 and the BIPM SI Brochure (9th edition) (reference).
Worked Example
15 Gigabit per Second equals 0.015 Terabit per Second.
15 Gbps × 0.001 = 0.015 Tbps
