Understanding Hexadecimal and Decimal Numbers

What is the Hexadecimal Number System?
The hexadecimal system (base-16) uses sixteen symbols to represent numbers:
0–9 represent values 0 to 9
A = 10, B = 11, C = 12, D = 13, E = 14, F = 15
Hexadecimal is popular in computer science, programming, and digital systems because it’s a compact way to represent binary numbers. Each hexadecimal digit corresponds to four binary digits (bits).
Example: Hex A = Binary 1010
Hex 1F = Binary 00011111

What is the Decimal Number System?
The decimal system (base-10) is the most commonly used system in everyday life. It uses digits 0–9, where each digit is a power of 10.
Example: Decimal 345 = 3 × 10² + 4 × 10¹ + 5 × 10⁰.

Why Convert Hexadecimal to Decimal?
Hexadecimal values are compact but not easily readable for everyday use. Converting them into decimal:
• Helps in programming and debugging
• Makes values more human-readable
• Useful in mathematics, electronics, and networking
• Essential for students learning number system conversions

Formula for Hexadecimal to Decimal Conversion

Decimal = (dₙ×16ⁿ) + (dₙ₋₁×16ⁿ⁻¹) + … + (d₁×16¹) + (d₀×16⁰)

Where:
dₙ = digit in hexadecimal (0–F)
n = position of the digit (starting from 0 on the right)

Examples of Hexadecimal to Decimal Conversion

Example: Hex A

A = 10

✅ Hex A = Decimal 10

Example: Hex 1C

(1×16¹) + (C×16⁰) = (1×16) + (12×1) = 28

✅ Hex 1C = Decimal 28

Example: Hex 2F

(2×16¹) + (F×16⁰) = (2×16) + (15×1) = 32 + 15 = 47

✅ Hex 2F = Decimal 47

Example: Hex 7B

(7×16¹) + (B×16⁰) = (7×16) + (11×1) = 112 + 11 = 123

✅ Hex 7B = Decimal 123

Example: Hex FF

(F×16¹) + (F×16⁰) = (15×16) + (15×1) = 240 + 15 = 255

✅ Hex FF = Decimal 255

Example: Hex 1A3

(1×16²) + (A×16¹) + (3×16⁰) = (1×256) + (10×16) + (3×1) = 256 + 160 + 3 = 419

✅ Hex 1A3 = Decimal 419
