Bits to Bytes
A bit is the smallest unit of digital information, a single 0 or 1, the base unit for network speeds like Mbps. A byte is 8 bits, the basic unit for measuring file sizes and storage capacity. 1 bit equals 0.125 B, so converting between them is a matter of multiplying by that fixed factor — type any value into the converter below and both sides update instantly as you type.
Both units belong to data, measured here against data's base unit (bit) — every other data unit on this site converts through that same reference point, which is why the table below can also be read as a quick cross-check against nearby values.
Formula
B = bit × 0.125
bit = B × 8
Worked example: 5 bit × 0.125 = 0.625 B.

Frequently asked
- How many Bytes in a bit?
- 1 bit equals 0.125 B.
- How do I convert Bits to Bytes?
- Multiply the value in bit by 0.125 to get B. The converter above does this instantly as you type.
- Is the conversion exact?
- Yes — Bit and Byte are both defined by a fixed conversion factor to data's base unit (bit), so the result shown is exact to the precision displayed, not an approximation.
