Convert Bytes to Bits (B to bit)
1 byte (B) = 8 bits (bit). 1 bit = 0.125 B. Example: 1 B = 1 × 8 = 8 bit.

How to Convert Byte to Bit
- 1 B = 8 bit
- 1 bit = 0.125 B
- Example: convert 1 B to bit: 1 B = 1 × 8 bit = 8 bit
Formula
bit = B × 8
Derivation from SI units:
- 1 byte = 8 bits (an octet).
- The basic unit of information: one binary digit, 0 or 1.
Both units are defined exactly, so the factor is exact. Byte definition: byte; Bit definition: bit.
Worked examples
- 1 B is 8 bit.
1 B × 8 = 8 bit - A 16 B value is 128 bit.
16 B × 8 = 128 bit

Where it's used
Sizes in bytes are converted to bits for network transfer times, serial protocols and digital-logic work, where data moves one bit at a time. Multiply by 8.

Frequently asked questions
Why is a byte 8 bits?
Eight bits hold 256 values, enough for a character set, and became the standard with the IBM System/360 in the 1960s; the unambiguous name is “octet”.
How many bits are in 1 byte?
1 B = 8 bit.
How do I convert bytes to bits?
Multiply the value in B by 8. For example, 1 B × 8 = 8 bit.
Is the B to bit conversion exact?
Yes. Both units are defined exactly, and 1 B is exactly 8 bit.
