How to convert bits to bytes
B = b × 0.125Multiply the value in bits by 0.125. To go the other way, multiply by 8 (or divide by 0.125).
A bit is smaller than a byte: it takes 8 bits to make one byte.
Worked examples

About the units
Bit (b)
A single binary digit, 0 or 1.
Byte (B)
Eight bits; the basic addressable unit of memory. One byte equals 8 bits (b).
Frequently asked questions
How many bytes are in one bit?
There are 0.125 bytes in one bit, and this value is exact by definition.
How do I convert bits to bytes?
Multiply the number of bits by 0.125. For example, 10 b × 0.125 = 1.25 B.
How many bits are in one byte?
One byte equals 8 bits. That is the reverse factor, 1 ÷ 0.125.
What is 10 bits in bytes?
10 b = 1.25 B.
Is this b to B converter accurate?
Yes. Both units are defined exactly in terms of SI units, so the conversion factor is exact; results are shown to 12 significant figures by default and you can change precision in the converter. Calculations run in your browser using the same tested engine that generated this page.
