1 byte (B) = 8 bits (bit). To convert, multiply by 8: bit = B × 8. For example, 5 B = 40 bit.
bit = B × 8

The two units
Byte (B). Eight bits. File sizes and memory are counted in bytes.
Bit (bit). A single binary digit, 0 or 1. Network speeds are quoted in bits per second.
Because both units are defined in terms of the same base unit, the factor 8 is exact, not a rounded measurement.
