Convert Kilobytes to Bits (kB to bit)
1 kilobyte (kB) = 8000 bits (bit). 1 bit = 0.000125 kB. Example: 15 kB = 15 × 8000 = 120000 bit.

How to Convert Kilobyte to Bit
- 1 kB = 8000 bit
- 1 bit = 0.000125 kB
- Example: convert 15 kB to bit: 15 kB = 15 × 8000 bit = 120000 bit
Formula
bit = kB × 8000
Derivation from SI units:
- 1 kB = 1000 bytes = 8000 bits (decimal, SI).
- The basic unit of information: one binary digit, 0 or 1.
Both units are defined exactly, so the factor is exact. Kilobyte definition: kilobyte; Bit definition: bit.
Worked examples
- A reading of 16 kB converts to 128000 bit.
16 kB × 8000 = 128000 bit - A value of 128 kB is 1024000 bit.
128 kB × 8000 = 1024000 bit
