How to convert kibibytes to bits
To convert a measurement in kibibytes to bits, multiply the value by 8,192. The conversion factor comes from the relationship between both units and the byte.
For example, to convert 5 KiB to bits: 5 × 8,192 = 40,960 bit.
What is a kibibyte?
A kibibyte is exactly 1,024 bytes (2^10), the binary counterpart of the kilobyte defined by the IEC. Use it when you mean the power-of-two value. The IEC introduced the binary prefixes (kibi, mebi, gibi, ...) in 1998 to end the long-standing confusion between the decimal kilobyte (1,000 B) and the binary 1,024-byte unit that computing had informally called a kilobyte.
Common uses of kibibytes include: Memory and buffer sizes in software; Operating-system file-size reporting; Low-level programming and disk blocks; Any context needing an exact power-of-two size.
What is a bit?
A bit is the smallest unit of digital information, representing a single binary value of 0 or 1. Eight bits make one byte. The term 'bit', a contraction of 'binary digit', was coined by statistician John Tukey and popularized by Claude Shannon in his 1948 paper founding information theory. It is the fundamental unit on which all digital data is built.
Common uses of bits include: Network and internet speeds (Mbps, Gbps); Data transfer and bandwidth measurement; Encryption key lengths (128-bit, 256-bit); Color depth and audio bit rates.

Frequently asked questions
How many bits are in one kibibyte?
One kibibyte (KiB) equals 8,192 bits (bit). Multiply any value in kibibytes by 8,192 to convert to bits.
How do I convert kibibytes to bits?
Multiply the value in kibibytes by 8,192. For example, 5 KiB × 8,192 = 40,960 bit.
How do I convert bits to kibibytes?
Multiply the value in bits by 0.000122070313, or divide by 8,192. Use the swap button on the converter above to reverse the direction.
Is the kibibyte to bit conversion exact?
Decimal units (KB, MB, GB) use powers of 1000 per SI; binary units (KiB, MiB, GiB) use powers of 1024 per IEC. Both are exact — just be sure you are using the right family, since storage is often sold in decimal but reported by operating systems in binary.
What is the formula for kibibytes to bits?
The formula is: bit = KiB × 8,192. This comes from the definition of both units relative to the byte.
