Gibit/s to Gbps
1 gibibit per second equals 1.073741824 gigabits per second exactly.
How to convert gibibits per second to gigabits per second
To convert gibibits per second to gigabits per second, multiply the number of gibibits per second by 1.073741824. This factor is exact. To go the other way, multiply gigabits per second by 0.9313225746 (rounded).
gigabits per second = gibibits per second × 1.073741824
Example: 10 gibibits per second = 10.73741824 gigabits 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).

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).
