What Is Hexadecimal?
The hexadecimal number system is a base-16 system that uses:
- Numbers: 0–9
- Letters: A–F (where A = 10 and F = 15)
Hexadecimal is widely used in computing because it is a more readable representation of binary values.
What Is Decimal?
The decimal number system is the standard base-10 system used in everyday counting. It uses digits from 0 to 9 and positional values based on powers of 10.
How Hexadecimal to Decimal Conversion Works
Each digit in a hexadecimal number represents a power of 16, starting from right to left.
Hexadecimal Place Values
| Position | Value |
|---|---|
| Rightmost | 16⁰ |
| Next | 16¹ |
| Next | 16² |
| Next | 16³ |
Hexadecimal to Decimal Conversion Formula
Decimal Value = Σ (Hex Digit × 16^Position)
Example: Convert FF from Hex to Decimal
Step 1: Assign Decimal Values
F = 15
F = 15
Step 2: Apply Place Values
(15 × 16¹) + (15 × 16⁰)
Step 3: Calculate
(15 × 16) + (15 × 1)
= 240 + 15
= 255
✅ Final Answer: 255
