Gbps to GiB/s
1 gigabit per second equals 0.1164153218 gibibytes per second (rounded).
How to convert gigabits per second to gibibytes per second
To convert gigabits per second to gibibytes per second, multiply the number of gigabits per second by 0.1164153218. The factor is rounded to 10 significant digits. To go the other way, multiply gibibytes per second by 8.589934592.
gibibytes per second = gigabits per second × 0.1164153218
Example: 10 gigabits per second = 1.164153218 gibibytes 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).

Gibibyte Per Second (GiB/s)
1,073,741,824 bytes per second.
Gibibytes per second belong to the top of the speed range, where memory and fast storage move data in bulk. One gibibyte per second is 1,073,741,824 bytes per second. Multiplying by 8 gives 8,589,934,592 bits per second, so it is about 8.59 decimal gigabits per second and roughly 7.4 percent more than a decimal gigabyte per second.
The gi in the name stands for gigabinary, one of the contractions proposed in 1995 by an IUPAC committee. The IEC approved the finished prefixes in December 1998 as a way to separate binary multiples from SI ones. Later editions added further prefixes, and ISO/IEC 80000-13 now carries the binary prefix definitions. A gibibyte rate is easy to confuse with a gigabit rate, because the two differ by a factor of about 8.6, so conversions between them need care.
1 gibibyte per second = 8,589,934,592 bits per second (exactly).
