Bytes to bits Conversion
1 bytes (B) is equal to 8 bits (bit).
1 B = 8 bit
or
1 bit = 0.125 B
Formula
To convert a digital storage from bytes (B) to bits (bit), multiply the digital storage in bytes by 8
d(bit) = d(B) × 8
Examples:
Convert 1 bytes to bits:
d(bit) = 1B × 8 = 8 bit

Frequently asked questions
How do I convert bytes to bits?
Multiply the value in bytes by 8 to get the result in bits. For example, 5 B × 8 = 40 bit.
How many bits are in 1 bytes?
1 bytes (B) is equal to 8 bits (bit).
How do I convert bits back to bytes?
Use the inverse operation: divide the value in bits by 8 to get the result in bytes.
How accurate is the bytes to bits conversion?
The converter multiplies by the conversion factor 8 and rounds the result to 9 decimal places by default. You can increase or reduce the precision with the digits option on this page.
