How to convert bytes to bits
b = B × 8Multiply the value in bytes by 8. To go the other way, multiply by 0.125 (or divide by 8).
A byte is larger than a bit: one byte contains 8 bits.
Worked examples
- 1 byte1 B × 8 = 8 b
- 5 bytes5 B × 8 = 40 b
- 10 bytes10 B × 8 = 80 b
- 20 bytes20 B × 8 = 160 b
- 100 bytes100 B × 8 = 800 b

About the units
Byte (B)
Eight bits; the basic addressable unit of memory. One byte equals 8 bits (b).
Bit (b)
A single binary digit, 0 or 1.
Frequently asked questions
How many bits are in one byte?
There are 8 bits in one byte, and this value is exact by definition.
How do I convert bytes to bits?
Multiply the number of bytes by 8. For example, 10 B × 8 = 80 b.
How many bytes are in one bit?
One bit equals 0.125 bytes. That is the reverse factor, 1 ÷ 8.
What is 10 bytes in bits?
10 B = 80 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.
