What is Hexadecimal?
Hexadecimal (base-16) uses sixteen digits: 0-9 and A-F. It's widely used in computing for color codes, memory addresses, and binary data representation.
Common Uses
Hex numbers are commonly used in web development (CSS colors), programming (memory addresses), and digital systems (binary data representation).
How Decimal to Hex Conversion Works

Interesting History
Ancient Origins
The hexadecimal system has its roots in computer science and digital electronics. While decimal has been used for millennia, hexadecimal gained prominence in the 1960s with the rise of digital computers.
Computer Era
IBM brought hexadecimal to mainstream computing with their System/360 in 1964. The choice of base-16 was natural as it efficiently represents binary data - each hex digit represents exactly 4 binary digits.
Modern Usage
The widespread adoption of RGB color codes in the 1990s made hexadecimal familiar to web developers and designers. Today, hex is essential in programming, debugging, and digital design.
