How Hexadecimal to Decimal Conversion Works
Hexadecimal is a base-16 number system using digits 0-9 and letters A-F. Each position in a hex number represents a power of 16:
- The rightmost digit is multiplied by 16⁰ (1)
- The next digit to the left is multiplied by 16¹ (16)
- The next digit is multiplied by 16² (256)
- And so on with increasing powers of 16
For example, hex "1A" equals decimal 26 because: 1×16¹ + A(10)×16⁰ = 16 + 10 = 26
Conversion Examples
| Hexadecimal | Decimal | Calculation |
|---|---|---|
| A | 10 | A represents 10 in decimal |
| 1F | 31 | 1×16¹ + F(15)×16⁰ = 16 + 15 = 31 |
| FF | 255 | F(15)×16¹ + F(15)×16⁰ = 240 + 15 = 255 |
| 100 | 256 | 1×16² + 0×16¹ + 0×16⁰ = 256 + 0 + 0 = 256 |
| CAFE | 51,966 | C(12)×16³ + A(10)×16² + F(15)×16¹ + E(14)×16⁰ |
