Why is hexadecimal used in programming?

Hexadecimal provides a compact way to represent binary data. Each hex digit represents exactly 4 binary digits, making it easy to convert between hex and binary. It's commonly used for memory addresses, color codes, and debugging.

How do I convert hex to decimal?

Multiply each hex digit by its corresponding power of 16 and sum the results. For example: 2F₁₆ = 2×16¹ + F×16⁰ = 2×16 + 15×1 = 32 + 15 = 47₁₀

What are hex color codes?

Hex color codes use 6 hexadecimal digits to represent colors: #RRGGBB. Each pair represents the red, green, and blue components from 00 (none) to FF (maximum). For example, #FF0000 is pure red.

How does hex relate to binary?

Each hexadecimal digit corresponds to exactly 4 binary digits. This makes conversion easy: 1010₂ = A₁₆, 1111₂ = F₁₆. Hex is often used as a shorthand for binary in computing.
