How to Convert Manually
Use these steps to convert Gigabit per Second values to Megabyte per Second without the calculator.
- Write down the value in Gigabit per Second (Gbps) that you want to convert.
- Multiply that value by 125.
- For example, 10 Gigabit per Second × 125 = 1250 Megabyte per Second.
- Label the result as Megabyte per Second (MB-s).

About Gigabit per Second and Megabyte 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 megabyte per second (MB/s) equals 8,000,000 bits per second (8 Mbps). It is the standard unit for SSD and HDD benchmark results, USB transfer speeds, and file-copy throughput displays. One Gigabit per Second equals 125 Megabyte per Second (1 Gbps = 125 MB-s). Gigabit per Second is used in Gigabit and multi-gigabit fibre broadband (1–10 Gbps) and in data-centre server NICs and switches. Megabyte per Second is used in SSD sequential read/write benchmarks (500–7,000 MB/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.
