The bit
A bit is the smallest unit of digital information — a single 0 or 1. Eight bits make one byte. The bit is the natural unit for bandwidth (most network speeds are quoted in bits per second, not bytes).
Bits to Bytes Converter
1 bit = 0.125 B
1 bit equals 0.125 bytes. To convert bits to bytes, multiply the bit value by 0.125. For quick reference: 1 bit = 0.125 B, 5 bit = 0.625 B, 10 bit = 1.25 B, 100 bit = 12.5 B.
Formula
Bytes = Bits × 0.125Quick
How to convert bits to bytes

Real-world reference
A boolean flag is 1 bit. A 4K HDR stream uses around 25 megabits per second. In bytes, that gives you: 1 bit = 0.125 B, 10 bit = 1.25 B, 100 bit = 12.5 B.
Frequently asked questions
- How many bytes are in 1 bit?
- 1 bit equals 0.125 bytes.
- How do I convert bits to bytes?
- Multiply the bit value by 0.125. So x bit × 0.125 = the equivalent in B.
- What is 5 bits in bytes?
- 5 bits equals 0.625 bytes.
- What is 10 bits in bytes?
- 10 bits equals 1.25 bytes.
- What is 100 bits in bytes?
- 100 bits equals 12.5 bytes.
- How do I convert back from bytes to bits?
- Multiply the byte value by 8. For example, 1 B = 8 bit.
- Is the bit bigger than the byte?
- No. 1 bit is smaller than 1 byte. It takes 8 bits to equal 1 byte.
- Are these conversion factors exact?
- Yes. The factor of 0.125 is derived directly from the SI definitions of bit and byte.
About the bit and the byte
The byte
A byte is 8 bits — the smallest addressable unit on virtually every modern computer. ASCII text is one byte per character; UTF-8 ranges from 1 to 4 bytes per character.
