Gbps to Bps (Gbps to bit/s)
1 gigabit per second equals 1,000,000,000 bits per second exactly.
How to convert gigabits per second to bits per second
To convert gigabits per second to bits per second, multiply the number of gigabits per second by 1,000,000,000. This factor is exact. To go the other way, multiply bits per second by 1×10⁻⁹.
bits per second = gigabits per second × 1,000,000,000
Example: 10 gigabits per second = 10,000,000,000 bits 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).

Bit Per Second (bit/s)
The basic unit of data rate: one bit transferred each second.
Before there was a bit per second, there had to be a bit. The word is a contraction of binary digit, and John W. Tukey is credited with shortening it in a Bell Labs memo dated 9 January 1947. Claude Shannon then used it in print in his 1948 paper on the mathematical theory of communication, where he credited Tukey. Counting such bits against the clock gave engineers a way to compare telegraph lines, telephone circuits and computer links with one yardstick.
Today the bit per second is the base unit for data rates, written bit/s and often shortened to bps. It is not the same thing as the baud, which counts signalling events per second. The two agree only when each signal carries exactly one bit. Ten-megabit Ethernet over twisted pair, for instance, runs at 10 Mbit/s but sends about 20 million pulses per second because of its line coding. For scale, one cited figure puts the bare minimum for recognizable speech at around 800 bit/s, far below the 64 kbit/s of an ordinary digital phone line.
The bit per second is the reference unit for data transfer rate on this site.
