Convert Bytes to Kilobits (B to kbit)
1 byte (B) = 0.008 kilobits (kbit). 1 kbit = 125 B. Example: 15 B = 15 × 0.008 = 0.12 kbit.

How to Convert Byte to Kilobit
- 1 B = 0.008 kbit
- 1 kbit = 125 B
- Example: convert 15 B to kbit: 15 B = 15 × 0.008 kbit = 0.12 kbit
Formula
kbit = B ÷ 125
Derivation from SI units:
- 1 byte = 8 bits (an octet).
- 1 kbit = 1000 bits (SI prefix kilo = 10³).
- 1 B = 8 bit ÷ 1000 bit per kbit = 0.008 kbit
Both units are defined exactly, so the factor is exact. Byte definition: byte; Kilobit definition: kilobit.
Worked examples
- A reading of 512 B converts to 4.096 kbit.
512 B × 0.008 = 4.096 kbit - A value of 4096 B is 32.768 kbit.
4096 B × 0.008 = 32.768 kbit

Frequently asked questions
How many kilobits are in 1 byte?
1 B = 0.008 kbit.
How do I convert bytes to kilobits?
Multiply the value in B by 0.008, or divide it by 125. For example, 15 B × 0.008 = 0.12 kbit.
Is the B to kbit conversion exact?
Yes. Both units are defined exactly, and 1 B is exactly 0.008 kbit.
