Kilobytes to Kilobits
A kilobyte is 1,000 bytes (decimal), used by storage manufacturers and some operating systems for file sizes. A kilobit is 1,000 bits, commonly used in internet speed ratings like kbps for older dial-up connections. 1 kB equals 8 kbit, so converting between them is a matter of multiplying by that fixed factor — type any value into the converter below and both sides update instantly as you type.
Both units belong to data, measured here against data's base unit (bit) — every other data unit on this site converts through that same reference point, which is why the table below can also be read as a quick cross-check against nearby values.
Formula
kbit = kB × 8
kB = kbit × 0.125
Worked example: 5 kB × 8 = 40 kbit.

Frequently asked
- How many Kilobits in a kilobyte?
- 1 kB equals 8 kbit.
- How do I convert Kilobytes to Kilobits?
- Multiply the value in kB by 8 to get kbit. The converter above does this instantly as you type.
- Is the conversion exact?
- Yes — Kilobyte and Kilobit are both defined by a fixed conversion factor to data's base unit (bit), so the result shown is exact to the precision displayed, not an approximation.
