In telecommunications and computing, bit rate (bitrate or as a variable R) is the number of bits that are conveyed or processed per unit of time.
|bit per second||bit/s||1||1|
|Metric prefixes (SI)|
|kilobit per second||kbit/s||103||10001|
|megabit per second||Mbit/s||106||10002|
|gigabit per second||Gbit/s||109||10003|
|terabit per second||Tbit/s||1012||10004|
|Binary prefixes (IEC 80000-13)|
|kibibit per second||Kibit/s||210||10241|
|mebibit per second||Mibit/s||220||10242|
|gibibit per second||Gibit/s||230||10243|
|tebibit per second||Tibit/s||240||10244|
The bit rate is expressed in the unit bit per second (symbol: bit/s), often in conjunction with an SI prefix such as kilo (1 kbit/s = 1,000 bit/s), mega (1 Mbit/s = 1,000 kbit/s), giga (1 Gbit/s = 1,000 Mbit/s) or tera (1 Tbit/s = 1,000 Gbit/s). The non-standard abbreviation bps is often used to replace the standard symbol bit/s, so that, for example, 1 Mbps is used to mean one million bits per second.
In most computing and digital communication environments, one byte per second (symbol: B/s) corresponds to 8 bit/s.
