Convert binary numbers to decimal, octal, and hexadecimal with bit visualization.
Frequently Asked Questions
How do I convert binary to decimal?
Multiply each binary digit by 2 raised to its position power (starting from 0 on the right), then sum all values. Example: 1011 = 8+0+2+1 = 11.
Can I convert binary fractions?
Yes, enter a binary number with a decimal point like 101.11. The fractional part uses negative powers of 2.
How are negative binary numbers handled?
Prefix with a minus sign, or enable two's complement mode to interpret the input as a signed binary number.
What is bit visualization?
Bit visualization shows each binary digit as a cell with its positional value, helping you understand how each bit contributes to the result.
Can I convert to other number systems?
Yes, the tool simultaneously shows results in decimal, octal, and hexadecimal.
What is the maximum binary length?
Up to 53 significant bits for integer conversion, matching JavaScript's Number precision.
Does it work offline?
Yes, all computation happens in your browser with no server requests needed.
What is two's complement?
Two's complement represents negative numbers in binary. The MSB indicates the sign. Enable the option to interpret input as two's complement.
