Gibit/s to MB/s
1 gibibit per second equals 134.217728 megabytes per second exactly.
How to convert gibibits per second to megabytes per second
To convert gibibits per second to megabytes per second, multiply the number of gibibits per second by 134.217728. This factor is exact. To go the other way, multiply megabytes per second by 0.007450580597 (rounded).
megabytes per second = gibibits per second × 134.217728
Example: 10 gibibits per second = 1,342.17728 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
Gibibit Per Second (Gibit/s)
1,073,741,824 bits per second.
At more than a billion bits each second, the gibibit per second suits fast storage buses and memory links. Its value is 1,073,741,824 bits per second, the product of 2 to the power 30, and it is about 7.4 percent larger than the decimal gigabit per second. Dividing by 8 gives 134,217,728 bytes per second, the figure Wikipedia lists for this unit.
The name was coined in the mid 1990s. A committee of IUPAC proposed kibi, mebi, gibi and tebi in 1995 as contractions of kilobinary, megabinary, gigabinary and terabinary. The IEEE then took the idea to ISO and the IEC and changed the symbols to the two-letter forms still used, so the unit is written Gibit/s. ISO 80000-1 defined the prefixes in 2009. Because the prefixes sit outside the SI, vendors of networking gear usually still quote plain gigabits, and Gibit/s mainly appears in technical specifications.
1 gibibit per second = 1,073,741,824 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).
