How to Convert Manually
Use these steps to convert Gigabit per Second values to Kilobit per Second without the calculator.
- Write down the value in Gigabit per Second (Gbps) that you want to convert.
- Multiply that value by 1000000.
- For example, 10 Gigabit per Second × 1000000 = 10000000 Kilobit per Second.
- Label the result as Kilobit per Second (Kbps).

About Gigabit per Second and Kilobit 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 kilobit per second (Kbps) equals 1,000 bits per second (SI decimal prefix). It is the standard unit for slow internet connections, audio streaming, and legacy modem speeds. One Gigabit per Second equals 1000000 Kilobit per Second (1 Gbps = 1000000 Kbps). Gigabit per Second to Kilobit 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 dial-up and early DSL connections (56 Kbps – 1 Mbps).
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 15000000 Kilobit per Second.
15 Gbps × 1000000 = 15000000 Kbps
