Convert Kilobits to Bytes (kbit to B)
1 kilobit (kbit) = 125 bytes (B). 1 B = 0.008 kbit. Example: 15 kbit = 15 × 125 = 1875 B.

How to Convert Kilobit to Byte
- 1 kbit = 125 B
- 1 B = 0.008 kbit
- Example: convert 15 kbit to B: 15 kbit = 15 × 125 B = 1875 B
Formula
B = kbit × 125
Derivation from SI units:
- 1 kbit = 1000 bits (SI prefix kilo = 10³).
- 1 byte = 8 bits (an octet).
- 1 kbit = 1000 bit ÷ 8 bit per B = 125 B
Both units are defined exactly, so the factor is exact. Kilobit definition: kilobit; Byte definition: byte.
Worked examples
- A reading of 16 kbit converts to 2000 B.
16 kbit × 125 = 2000 B - A value of 128 kbit is 16000 B.
128 kbit × 125 = 16000 B

Where it's used
Kilobits are used for telecom data quantities, while bytes appear in file and memory sizes. Both measure amount of digital information, so the conversion is a fixed factor.
