Gbps to MiB/s
1 gigabit per second equals 119.2092896 mebibytes per second (rounded).
How to convert gigabits per second to mebibytes per second
To convert gigabits per second to mebibytes per second, multiply the number of gigabits per second by 119.2092896. The factor is rounded to 10 significant digits. To go the other way, multiply mebibytes per second by 0.008388608.
mebibytes per second = gigabits per second × 119.2092896
Example: 10 gigabits per second = 1,192.092896 mebibytes 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
Gigabit Per Second (Gbps)
1,000,000,000 bits per second. Fiber and Ethernet speeds are quoted in Gbps.
Gigabit Ethernet came in two stages. IEEE 802.3z, produced in June 1998, was the first version and required optical fiber. IEEE 802.3ab, ratified in 1999, defined 1000BASE-T over four twisted pairs of ordinary copper cabling, which is what turned a backbone technology into something that could reach desktops. Over time, one gigabit per second became a built-in feature of many computers.
A gigabit per second is 1,000,000,000 bit/s, or 125 MB/s once the eight bits in a byte are accounted for. At that speed an ideal transfer of a 4.7 GB single-layer DVD image takes about 38 seconds. Ten Gigabit Ethernet, first defined in IEEE 802.3ae in 2002 and extended to twisted pair by 802.3an in 2006, multiplies this by ten and is common in data centers. Cable and DSL providers also quote gigabit figures; the G.fast DSL standard from 2014 tops out at 1 Gbit/s.
1 gigabit per second = 1,000,000,000 bits per second (exactly).

Mebibyte Per Second (MiB/s)
1,048,576 bytes per second (8.39 Mbps). Used by some operating systems and storage tools.
Mebibyte is one of the newest words in computing. In December 1998 the IEC approved names for binary multiples, published in 1999 as an amendment to IEC 60027-2. Each keeps the first two letters of its SI counterpart and adds bi for binary, so mebi stands for 2²⁰. The aim was to stop mega meaning 10⁶ in telecommunications and storage but 2²⁰ in memory, a split that left room for incompatibility.
A mebibyte per second is 1,048,576 bytes per second, about 8.39 Mbit/s, so it is roughly 4.9 percent larger than 1 MB/s. Some operating systems and tools divide by 1,024 and then print the result with a plain MB label, so one program may show 11.9 for a transfer that another shows as 12.5. For example, a 100 Mbit/s link carries about 11.92 MiB/s at most. The IEEE chose to keep SI meanings in its own standards, allowing base-two use of mega only when explicitly noted.
1 mebibyte per second = 8,388,608 bits per second (exactly).
