Bytes to Bits Converter
1 byte = 8 bits
1 byte equals 8 bits
How to convert bytes to bits
Lowercase b means bit; uppercase B means byte (8 bits). Decimal kB, MB and GB use powers of 1000; binary KiB, MiB and GiB use powers of 1024. Choose the label that matches the source measurement.
b = B × 8One byte is 8 bits, so a single multiplication converts any value.
80 b = 10 × 8Bytes to bits conversion table

About these units
byteB
Eight bits. The standard addressable unit of computer memory.
bitb
The smallest unit of digital information: a single binary digit.
Sources and precision
Table results are rounded to 8 significant digits; formula constants may be rounded to 10. Worked example answers use 6 significant digits. The converter starts at 6 significant digits and lets you change display precision. Calculations use the stored factors without intermediate rounding. Exact unit definitions do not make an input measurement more precise; conventional and measured factors follow the assumptions stated here.
