Mibit/s to MB/s
1 mebibit per second equals 0.131072 megabytes per second exactly.
How to convert mebibits per second to megabytes per second
To convert mebibits per second to megabytes per second, multiply the number of mebibits per second by 0.131072. This factor is exact. To go the other way, multiply megabytes per second by 7.629394531 (rounded).
megabytes per second = mebibits per second × 0.131072
Example: 10 mebibits per second = 1.31072 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
Mebibit Per Second (Mibit/s)
1,048,576 bits per second.
Mebibits per second sit one binary step above the kibibit and measure the speeds of links and streams when a strict power of two is wanted. Mebi comes from mega with the same bi ending, and the quantity is 2 to the power 20, or 1,048,576. The IEC prefixes were meant to end a long confusion in computing, where kilo, mega and giga had been used for powers of 2 even though the SI gives them powers of 10.
The arithmetic is simple. One mebibit per second is 1,048,576 bits per second, which equals 131,072 bytes per second and is about 4.86 percent more than a decimal megabit per second. Wikipedia's article on data-rate units notes that decimal prefixes are typically used for data rates, so the mebibit per second is a precise but uncommon alternative. The IEEE adopted the prefix names in 1996 with the symbols Ki, Mi and Gi, and its standard 1541-2002 became a full-use standard in 2005.
1 mebibit per second = 1,048,576 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).
