GB/s to MB/s
1 gigabyte per second equals 1,000 megabytes per second exactly.
How to convert gigabytes per second to megabytes per second
To convert gigabytes per second to megabytes per second, multiply the number of gigabytes per second by 1,000. This factor is exact. To go the other way, multiply megabytes per second by 0.001.
megabytes per second = gigabytes per second × 1,000
Example: 10 gigabytes per second = 10,000 megabytes per second.
Network speeds are quoted in bits per second (lowercase b), while file sizes use bytes (uppercase B). Divide Mbps by 8 for MB/s.
About these units
Gigabyte Per Second (GB/s)
1,000,000,000 bytes per second (8 Gbps). Memory and fast SSD bandwidth.
The gigabyte grew out of the same habit of rounding 1,024 to 1,000. In 1998 the IEC published binary prefixes, reserving gigabyte for the decimal value of 1,000,000,000 bytes and naming 1,073,741,824 bytes a gibibyte. Disk makers have used decimal capacities since the first disk drive, which is why a drive sold as 400 GB can appear as about 372 GB in Windows, while macOS, iOS and Android report decimal sizes.
A gigabyte per second is 1,000,000,000 bytes per second, equal to 8 Gbit/s. At that rate a 25 GB single-layer Blu-ray worth of data transfers in 25 seconds, and one hour of standard-definition video at 2.2 Mbit/s, about 1 GB, would pass in a single second. A 10 Gigabit Ethernet link, by comparison, tops out near 1.25 GB/s. Memory and storage interfaces tend to be described in this unit because their bandwidth is far beyond what ordinary networks offer.
1 gigabyte per second = 8,000,000,000 bits per second (exactly).

Megabyte Per Second (MB/s)
1,000,000 bytes per second (8 Mbps). Disk and download speeds are shown in MB/s.
Megabytes per second inherit all the confusion of the megabyte itself. The word has meant 1,000,000 bytes in networking, hard drives and DVDs, 1,048,576 bytes for memory under Microsoft Windows, and 1,024,000 bytes for the 3.5-inch floppy disk marketed as 1.44 MB, which actually held 1,474,560 bytes. In 1999 the IEC defined megabyte as 10⁶ bytes and mebibyte as 2²⁰ bytes, and by the end of 2009 the IEEE, EU, ISO and NIST had adopted that standard.
As a rate, 1 MB/s is 1,000,000 bytes per second, or 8 Mbit/s. File copies, game installers and disk benchmarks usually show MB/s, while internet plans use Mbit/s, so a 100 Mbit/s plan tops out near 12.5 MB/s. As a feel for size, about one minute of 128 kbit/s MP3 audio fits in roughly 1 MB, so a link carrying 1 MB/s moves about a minute of such audio every second.
1 megabyte per second = 8,000,000 bits per second (exactly).
