Convert Kilobytes to Kilobits (kB to kbit)
1 kilobyte (kB) = 8 kilobits (kbit). 1 kbit = 0.125 kB. Example: 15 kB = 15 × 8 = 120 kbit.

How to Convert Kilobyte to Kilobit
- 1 kB = 8 kbit
- 1 kbit = 0.125 kB
- Example: convert 15 kB to kbit: 15 kB = 15 × 8 kbit = 120 kbit
Formula
kbit = kB × 8
Derivation from SI units:
- 1 kB = 1000 bytes = 8000 bits (decimal, SI).
- 1 kbit = 1000 bits (SI prefix kilo = 10³).
- 1 kB = 8000 bit ÷ 1000 bit per kbit = 8 kbit
Both units are defined exactly, so the factor is exact. Kilobyte definition: kilobyte; Kilobit definition: kilobit.
Worked examples
- A reading of 16 kB converts to 128 kbit.
16 kB × 8 = 128 kbit - A value of 128 kB is 1024 kbit.
128 kB × 8 = 1024 kbit
