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

About Megabit per Second and Megabyte 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 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 Megabit per Second equals 0.125 Megabyte per Second (1 Mbps = 0.125 MB-s). Megabit per Second to Megabyte 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 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.
Conversion factors per NIST Special Publication 811 and the BIPM SI Brochure (9th edition) (reference).
Worked Example
15 Megabit per Second equals 1.875 Megabyte per Second.
15 Mbps × 0.125 = 1.875 MB-s
