Terabit per second (symbol Tbit/s or Tb/s, sometimes abbreviated "Tbps") is a unit of data transfer rate equal to: Gigabit per second (symbol Gbit/s or Gb/s, often abbreviated "Gbps") is a unit of data transfer rate equal to: Megabit per second (symbol Mbit/s or Mb/s, often abbreviated "Mbps") is a unit of data transfer rate equal to: Kilobit per second (symbol kbit/s or kb/s, often abbreviated "kbps") is a unit of data transfer rate equal to: These units are often used in a manner inconsistent with the IEC standard. It also clarifies that the SI prefixes are used only to mean powers of 10 and never powers of 2. ![]() The name is derived from the first two letters of the original SI prefixes followed by bi (short for binary). This standard, approved in 1998, introduced the prefixes kibi-, mebi-, gibi-, tebi-, pebi-, and exbi- to be used in specifying binary multiples of a quantity. In 1999, the IEC published Amendment 2 to " IEC 60027-2: Letter symbols to be used in electrical technology – Part 2: Telecommunications and electronics". In the context of data rates, however, typically only decimal prefixes are used, and they have their standard SI interpretation. The letter K is often used as a non-standard abbreviation for 1,024, especially in "KB" to mean KiB, the kilobyte in its binary sense. The binary prefixes were introduced in 1998 by the International Electrotechnical Commission (IEC) and in IEEE 1541-2002 which was reaffirmed on 27 March 2008. In both the SI and ISQ, the prefix k stands for kilo, meaning 1,000, while Ki is the symbol for the binary prefix kibi-, meaning 1,024. The Institute of Electrical and Electronics Engineers (IEEE) uses the symbol b for bit. The abbreviation bps is often used to mean bit/s, so that when a 1 Mbps connection is advertised, it usually means that the maximum achievable bandwidth is 1 Mbit/s (one million bits per second), which is 0.125 MB/s ( megabyte per second), or about 0.1192 MiB/s ( mebibyte per second). ![]() In the context of data-rate units, one byte consists of 8 bits, and is synonymous with the unit octet. Altogether, it took 5 hours, 26 minutes, and 42 seconds.The ISQ symbols for the bit and byte are bit and B, respectively. ![]() To convert the decimal into seconds, multiply it by 60. To convert 0.445 hours to minutes, multiply by 60. If you want to use hours and minutes, separate out the whole number and decimal: you have 5 hours and 0.445 hours.In other words, it took 5.445 hours to transfer 134 GB at a rate of 7 MB/s. To convert this to hours, divide by 3,600, which is 5.445. So, you transferred 137,217 MB at a rate of 7 MB/s. First, convert GB to MB so you’re working with the same units in each part of the equation. For instance, say you transferred 134 GB at a rate of 7 MB/s.If you want to solve for the transfer time (T) instead, input the amount of data (A) and the rate or speed (S) of transfer into the equation T = A ÷ S. Divide the amount of data by the transfer speed to find the transfer time. ![]()
