Kilobits to Kilobytes
A kilobit is 1,000 bits, commonly used in internet speed ratings like kbps for older dial-up connections. A kilobyte is 1,000 bytes (decimal), used by storage manufacturers and some operating systems for file sizes. 1 kbit equals 0.125 kB, 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
kB = kbit × 0.125
kbit = kB × 8
Worked example: 5 kbit × 0.125 = 0.625 kB.

Frequently asked
- How many Kilobytes in a kilobit?
- 1 kbit equals 0.125 kB.
- How do I convert Kilobits to Kilobytes?
- Multiply the value in kbit by 0.125 to get kB. The converter above does this instantly as you type.
- Is the conversion exact?
- Yes — Kilobit and Kilobyte 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.
