How to convert bits to kilobytes
To convert a measurement in bits to kilobytes, multiply the value by 0.000125. The conversion factor comes from the relationship between both units and the byte.
For example, to convert 5 bit to kilobytes: 5 × 0.000125 = 0.000625 KB.
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.
What is a kilobyte?
A kilobyte is 1,000 bytes under the SI decimal convention. Note that some contexts historically used 1,024 bytes; the 1,024-byte unit is properly the kibibyte (KiB). The 'kilo' prefix means 1,000 in SI, but early computing loosely used kilobyte for 1,024 bytes because it is close to 2^10. This ambiguity led the IEC to introduce the binary 'kibibyte' in 1998 to keep the two meanings distinct.
Common uses of kilobytes include: Small text documents and configuration files; Email message sizes; Web page and icon asset sizes; Marketing of storage where decimal units are used.

Frequently asked questions
How many kilobytes are in one bit?
One bit (bit) equals 0.000125 kilobytes (KB). Multiply any value in bits by 0.000125 to convert to kilobytes.
How do I convert bits to kilobytes?
Multiply the value in bits by 0.000125. For example, 5 bit × 0.000125 = 0.000625 KB.
How do I convert kilobytes to bits?
Multiply the value in kilobytes by 8,000, or divide by 0.000125. Use the swap button on the converter above to reverse the direction.
Is the bit to kilobyte 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 bits to kilobytes?
The formula is: KB = bit × 0.000125. This comes from the definition of both units relative to the byte.
