Bytes to bits converter
Bits (b)
1 byte = 8 bits
How to convert bytes to bits
b = B × 8
Multiply the number of bytes by 8 to get bits. Going the other way, divide by 8 (or multiply by 0.125).
One byte is exactly defined as 8 bits (to 12 significant figures), and one bit is 0.125 bytes.
Worked examples
- Convert 5 bytes: 5 × 8 = 40 40 bits.
- Convert 12.5 bytes: 12.5 × 8 = 100 100 bits.
- Convert 250 bytes: 250 × 8 = 2,000 2,000 bits.
