Hexadecimal is a numeral system that uses a base of 16, which is represented by the symbols 0-9 and A-F. It is often used in computer programming because it is a more efficient way to represent binary data. In other words, Hexadecimal is a convenient way to describe a string of binary code. Computer system designers and programmers widely use hexadecimal numerals. Each hexadecimal digit represents four binary digits (bits), allowing a more human-friendly representation of binary-coded values. One hexadecimal digit represents a nibble (4 bits). For example, a single byte can have values ranging from 00000000 to 11111111 in binary form, which can be conveniently represented as 00 to FF in Hexadecimal. Hexadecimal is also used in the red-green-blue color system in computers. If you want to know how to convert text into Hexadecimal, you can use our online Hex Converter tool.
