Bps to KiB/s (bit/s to KiB/s)
1 bit per second equals 0.0001220703125 kibibytes per second exactly.
How to convert bits per second to kibibytes per second
To convert bits per second to kibibytes per second, multiply the number of bits per second by 0.0001220703125. This factor is exact. To go the other way, multiply kibibytes per second by 8,192.
kibibytes per second = bits per second × 0.0001220703125
Example: 10 bits per second = 0.001220703125 kibibytes 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
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.

Kibibyte Per Second (KiB/s)
1,024 bytes per second.
File-transfer dialogs and download managers often show a speed in kilobytes per second, and the kibibyte per second is the unambiguous form of that reading. A kibibyte is 1,024 bytes. The kilobyte had long been used for that number, especially for memory, because 1,024 is close to 1,000. In 1998 the IEC introduced kibibyte, KiB, and said that kilobyte should mean 1,000 bytes only.
Real software has been slow to follow. Windows divides sizes by 1,024, so a file of 65,536 bytes appears as 64 KB, while recent versions of macOS show the same file as 66 kB. For a rate, one kibibyte per second is 1,024 bytes per second, which is 8,192 bits per second and about 1.024 decimal kilobytes per second. It is eight times the kibibit per second, since a byte holds eight bits.
1 kibibyte per second = 8,192 bits per second (exactly).
