Bytes to Bits
A byte is 8 bits, the basic unit for measuring file sizes and storage capacity. A bit is the smallest unit of digital information, a single 0 or 1, the base unit for network speeds like Mbps. 1 B equals 8 bit, 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
bit = B × 8
B = bit × 0.125
Worked example: 5 B × 8 = 40 bit.

Frequently asked
- How many Bits in a byte?
- 1 B equals 8 bit.
- How do I convert Bytes to Bits?
- Multiply the value in B by 8 to get bit. The converter above does this instantly as you type.
- Is the conversion exact?
- Yes — Byte and Bit 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.
