Byte to Bit Converter
Digital storage · unit-converter
Convert Byte to Bit with fixed input and output units, a step-by-step formula line, and reference tables. This hub uses decimal byte units (kB, MB, GB, …) and decimal megabits; the main converter also includes binary (KiB, MiB, …) units.

About Byte
The byte is eight bits and is the usual addressable unit for files and memory. This converter expresses every unit in byte-equivalents using fixed factors.
About Bit
A bit is a binary digit. Here 1 byte = 8 bits, so the byte-equivalent of one bit is 0.125 bytes. Networking speeds often use bits per second.
How to convert bytes to bits
1 byte is equal to 8 bit in this tool (values are compared in byte-equivalents):
1 b = (1 B ÷ 0.125 B) bit = 8 bit
1 byte = 8 bits exactly.
Each byte counts as 1 bytes and each bit as 0.125 bytes, so one b equals 1 ÷ 0.125 bit = 8 bit.
Let d(b) be the numeric amount in Byte (b), and d(bit) the amount in Bit (bit). Then:
d(bit) = d(b) × (1 / 0.125)
Equivalently, divide by how many b fit into one bit (bytes per bit divided by bytes per b):
d(bit) = d(b) ÷ 0.125
Or: bit = byte ÷ 0.125
Examples
Example #1: Convert 1 b to bit
1 b = 1 b × (1/0.125) bit = 8 bit
1 b = 1 b ÷ 0.125 = 8 bit
Example #2: Convert 10 b to bit
10 b = 10 b × (1/0.125) bit = 80 bit
10 b = 10 b ÷ 0.125 = 80 bit
Summary
To convert Byte to Bit, multiply the value in b by the ratio of bytes per b divided by bytes per bit. Equivalently: value_bit = value_b × (1 / 0.125). Numerically, 1 b equals 8 bit.
Relationship context
You are converting between byte-based units (decimal SI: kB, MB, GB, …) (Bytes) and bit-based units (converted via 8 bits per byte) (Bits). Bit units are mapped through 8 bits per byte, then scaled with the same decimal prefixes as byte units. The numeric factor is 8.000000e+0.
