Convert Byte to Bit

One B equals 8 bit. This converter allows you to easily convert between Byte and Bit in real time.

Formula

B × 8 = bit

Example: 1 B = 8 bit

What is Byte?

The byte is the fundamental unit of digital data, consisting of 8 bits. One byte is enough to represent a single ASCII character such as a letter or digit. In UTF-8 encoding, a Japanese character typically requires 3 bytes. All larger data units (KB, MB, GB, TB) are built upon the byte. It serves as the basic addressable unit in computer memory and storage systems.

What is Bit?

The bit is the smallest unit of information, representing a binary value of either 0 or 1. The word is short for "binary digit." Eight bits make up one byte. Internet connection speeds are measured in bits per second (bps), so a 1 Gbps fiber connection transfers one billion bits per second. Encryption strength (128-bit, 256-bit) and CPU architecture (32-bit, 64-bit) are also expressed in bits, making it a foundational unit in computing.
