How to Convert Hexadecimal to Decimal

Hexadecimal (base-16) uses digits 0–9 and A–F. To convert to decimal, multiply each hex digit by the power of 16 corresponding to its position and sum the results, starting from the rightmost digit at exponent 0.

Example: Convert 2F to Decimal

• F (15) × 16⁰ = 15
• 2 × 16¹ = 32

Sum = 32 + 15 = 47 → Decimal 47

Why It Matters

Hexadecimal is widely used by developers to condense binary for readability. Understanding the conversion is critical for memory addresses, data representation, networking, and low-level programming.
