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

About Megabyte per Second and Gigabyte per Second
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. The gigabyte per second (GB/s) equals 8,000,000,000 bits per second (8 Gbps). It is used for high-end NVMe storage benchmarks, PCIe bandwidth, and GPU memory bandwidth specifications. One Megabyte per Second equals 0.001 Gigabyte per Second (1 MB-s = 0.001 GB-s). Megabyte per Second to Gigabyte per Second conversion comes up most often in SSD sequential read/write benchmarks (500–7,000 MB/s) and in USB 3.0 (up to ~625 MB/s) and USB 3.2 transfers, typically when figures need restating for NVMe Gen 4/5 SSD throughput (5–14 GB/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 Megabyte per Second equals 0.015 Gigabyte per Second.
15 MB-s × 0.001 = 0.015 GB-s
