How to Convert Manually
Use these steps to convert Gigabit per Second values to Megabit per Second without the calculator.
- Write down the value in Gigabit per Second (Gbps) that you want to convert.
- Multiply that value by 1000.
- For example, 10 Gigabit per Second × 1000 = 10000 Megabit per Second.
- Label the result as Megabit per Second (Mbps).

About Gigabit per Second and Megabit 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 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. One Gigabit per Second equals 1000 Megabit per Second (1 Gbps = 1000 Mbps). Gigabit per Second is used in Gigabit and multi-gigabit fibre broadband (1–10 Gbps) and in data-centre server NICs and switches. Megabit per Second is used in home broadband and cable internet (25–1,000 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.
