Bits to Bytes Calculator

There are exactly 8 bits in 1 byte. This has been the standard since the early days of computing. A bit is a single binary digit (0 or 1), while a byte is a group of 8 bits that can represent values from 0 to 255.

The 8-bit byte became standard because it can represent 256 values (2^8), which is enough for all ASCII characters, basic color values, and common data types. Early computers experimented with 6-bit and 7-bit bytes, but 8 bits became the universal standard.

A bit (b) is the smallest unit of data, representing a single 0 or 1. A byte (B) is 8 bits grouped together. File sizes use bytes (KB, MB, GB), while network speeds typically use bits per second (Kbps, Mbps, Gbps).

Divide the Mbps value by 8. For example, a 100 Mbps connection can transfer about 12.5 megabytes per second (100 / 8 = 12.5). This is because internet speed is measured in megabits, not megabytes.

In decimal: 1 KB = 1,000 bytes = 8,000 bits. In binary: 1 KiB = 1,024 bytes = 8,192 bits. For networking calculations, the decimal value (8,000 bits per KB) is standard.

A nibble is 4 bits, or half a byte. Nibbles are used in hexadecimal notation where each hex digit (0-F) represents exactly one nibble. Two nibbles make one byte.
