Convert Kilobits to Kilobytes (kbit to kB)
1 kilobit (kbit) = 0.125 kilobytes (kB). 1 kB = 8 kbit. Example: 15 kbit = 15 × 0.125 = 1.875 kB.

How to Convert Kilobit to Kilobyte
- 1 kbit = 0.125 kB
- 1 kB = 8 kbit
- Example: convert 15 kbit to kB: 15 kbit = 15 × 0.125 kB = 1.875 kB
Formula
kB = kbit ÷ 8
Derivation from SI units:
- 1 kbit = 1000 bits (SI prefix kilo = 10³).
- 1 kB = 1000 bytes = 8000 bits (decimal, SI).
- 1 kbit = 1000 bit ÷ 8000 bit per kB = 0.125 kB
Both units are defined exactly, so the factor is exact. Kilobit definition: kilobit; Kilobyte definition: kilobyte.
Worked examples
- A reading of 16 kbit converts to 2 kB.
16 kbit × 0.125 = 2 kB - A value of 128 kbit is 16 kB.
128 kbit × 0.125 = 16 kB
