A byte is a digital information unit made of 8 bits.
Bytes became the practical unit for files, memory, characters, buffers, and storage in modern computing.
byte is used for file sizes, memory usage, binary data, buffers, storage, database fields, and online tool limits.
A bit is the smallest common digital information unit and represents a binary state.
Bits are central to binary logic, digital communication, encoding, compression, and data transmission.
bit is used in networking, protocols, encoding, compression, signals, and low-level data measurement.
Mathematically, bit (b) = byte (B) converted with the formula below.
1 B = 8 b
1 b = 0.125 B
Formula: value × 8
Example: 15 B = 120 b
Precision note: Use exactly 8 bits per byte. The result is exact for any byte input, including fractional byte values used in mathematical comparisons.
1 B = 8 b
1 b = 0.125 B
| Byte [B] | Bit [b] |
|---|---|
| 0.01 B | 0.08 b |
| 0.1 B | 0.8 b |
| 1 B | 8 b |
| 2 B | 16 b |
| 5 B | 40 b |
| 10 B | 80 b |
| 20 B | 160 b |
| 50 B | 400 b |
| 100 B | 800 b |
One byte contains exactly 8 bits.
1024 bytes equal 8192 bits.
A byte is made of 8 bits, so each byte contributes eight bits to the result.
