1 B = 8 bit
1 Byte (B) = 8 Bit (bit).
If you want to reverse convert, use Bit → Byte. 1 bit = 0.125 B. You can also explore the full Data converter page for more cross conversions.
Conversion formula
Byte to Bit formula: value in bit = value in B × 8.
Bit to Byte formula: value in B = value in bit × 0.125.
How to convert Byte to Bit
To convert Byte to Bit, multiply the value in B by 8. This gives the result in bit.
For example, 1 B = 8 bit and 10 B = 80 bit.
What is Byte?
Byte (B): A group of eight bits; one text character can require several bytes depending on its encoding. 1 B = 8 bit.
What is Bit?
Bit (bit): One binary digit with two possible states, usually written 0 or 1. 8 bit = 1 B; 1000 bit = 1 kbit.
FAQ
How many bit are in 1 byte?
There are 8 bit in 1 B.
Why can conversion results differ slightly?
Check the unit definition and rounding. US and imperial measures can differ; rounding intermediate values can also change the final digits.
How do I convert byte to bit?
Multiply the value in B by 8 to get the value in bit.
