Enter a binary, octal, decimal, or hexadecimal value and convert it to the other bases in real time
Hexadecimal represents numbers using 16 symbols: 0-9 and A-F, where A-F stand for 10-15. Because a single hex digit represents exactly 4 bits (four binary digits), hex is widely used to make binary easier for humans to read, such as in color codes (e.g. #FF8800) and memory addresses.
