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

About Gigabyte per Second and Megabyte per Second
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. 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 Gigabyte per Second equals 1000 Megabyte per Second (1 GB-s = 1000 MB-s). Gigabyte per Second to Megabyte per Second conversion comes up most often in NVMe Gen 4/5 SSD throughput (5–14 GB/s) and in PCIe 4.0 × 16 bandwidth (~32 GB/s), 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 Gigabyte per Second equals 15000 Megabyte per Second.
15 GB-s × 1000 = 15000 MB-s
