How to convert bytes to bits
To convert bytes to bits, multiply the value by the conversion factor 8. To go the other way, multiply by 0.125 (or divide by 8).
Worked example: 500 B to bit
- Write the value: 500 B
- Multiply by 8: 500 × 8
- Result: 4,000 bit

About Byte and Bit
What is a byte (B)?
A byte is 8 bits and usually stores one character of text.
What is a bit (bit)?
A bit is the smallest unit of digital data, either 0 or 1. Eight bits make one byte.
Binary vs decimal: this converter uses 1 KB = 1,024 bytes, which matches Windows, Android file managers and most upload forms. Storage manufacturers use 1 KB = 1,000 bytes, which is why a “128 GB” phone shows about 119 GB.
Where byte to bit conversion is used
Data storage conversions are needed for internet packages, file sizes, phone storage, upload limits on job and exam sites, and hard drives. Converting between bytes and bits is especially common when you compare products, read foreign specifications, or fill in forms that expect a specific unit.
