bit to byte
Convert bit (bit) to byte (B). Use an editable data storage converter, conversion formula, and reference table.
1 bit = 0.125 B
Conversion formula
One bit equals 0.125 byte. Multiply your value in bit by this factor to get byte. For the reverse conversion, divide by the same factor.
Worked example
To convert 5 bit:5 × 0.125 = 0.625 B
Conversion table
| bit (bit) | byte (B) |

| 1 | 0.125 |
| 2 | 0.25 |
| 5 | 0.625 |
| 10 | 1.25 |
| 25 | 3.125 |

| 1000 | 125 |
About these measurements
Data storage expresses a number of bits or bytes.
The base reference used here is the byte. One bit is 0.125 base units; one byte is 1 base units.
Important distinctions
Decimal prefixes use powers of 1,000; binary prefixes use powers of 1,024. One byte is eight bits.
Precision
The converter uses stored conversion factors and floating-point arithmetic. Results display up to ten significant digits, switching to scientific notation for very small or large values. Keep the precision of your original measurement when reporting results.
Common questions
How do I convert bit to B?
Multiply the quantity in bit by 0.125. You can also type the value into the converter above.
Can I reverse the conversion?
Yes. Use the swap button or open the byte to bit converter.
