How to Convert Manually
Use these steps to convert Gigabit per Second values to Gigabyte per Second without the calculator.
- Write down the value in Gigabit per Second (Gbps) that you want to convert.
- Multiply that value by 0.125.
- For example, 10 Gigabit per Second × 0.125 = 1.25 Gigabyte per Second.
- Label the result as Gigabyte per Second (GB-s).

About Gigabit per Second and Gigabyte 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 gigabyte per second (GB/s) equals 8,000,000,000 bits per second (8 Gbps). It is used for high-end NVMe storage benchmarks, PCIe bandwidth, and GPU memory bandwidth specifications. One Gigabit per Second equals 0.125 Gigabyte per Second (1 Gbps = 0.125 GB-s). Gigabit per Second to Gigabyte 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 NVMe Gen 4/5 SSD throughput (5–14 GB/s).
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 1.875 Gigabyte per Second.
15 Gbps × 0.125 = 1.875 GB-s
