Convert Bits to Kilobytes (bit to kB)
1 bit = 0.000125 kilobytes (kB). 1 kB = 8000 bit. Example: 15 bit = 15 × 0.000125 = 0.001875 kB.

How to Convert Bit to Kilobyte
- 1 bit = 0.000125 kB
- 1 kB = 8000 bit
- Example: convert 15 bit to kB: 15 bit = 15 × 0.000125 kB = 0.001875 kB
Formula
kB = bit ÷ 8000
Derivation from SI units:
- The basic unit of information: one binary digit, 0 or 1.
- 1 kB = 1000 bytes = 8000 bits (decimal, SI).
Both units are defined exactly, so the factor is exact. Bit definition: bit; Kilobyte definition: kilobyte.
Worked examples
- A reading of 16 bit converts to 0.002 kB.
16 bit × 0.000125 = 0.002 kB - A value of 128 bit is 0.016 kB.
128 bit × 0.000125 = 0.016 kB

Where it's used
Bits are used for network speeds (bits per second), while kilobytes appear in small files, emails and web pages. Both measure amount of digital information, so the conversion is a fixed factor.
