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

About Megabit per Second and Gigabit per Second
The megabit per second (Mbps) equals 1,000,000 bits per second (10⁶ bps). It is the dominant unit for consumer internet speed plans, Wi-Fi ratings, and video streaming requirements. 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. One Megabit per Second equals 0.001 Gigabit per Second (1 Mbps = 0.001 Gbps). Megabit per Second to Gigabit per Second conversion comes up most often in home broadband and cable internet (25–1,000 Mbps) and in Wi-Fi 5 and Wi-Fi 6 link rates, typically when figures need restating for Gigabit and multi-gigabit fibre broadband (1–10 Gbps).
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 Megabit per Second equals 0.015 Gigabit per Second.
15 Mbps × 0.001 = 0.015 Gbps
