Working Principle

Hexadecimal (base-16) is a positional numeral system with a radix of 16. Each digit position represents a power of 16, starting from the rightmost digit (160). The decimal value is calculated by multiplying each digit by 16 raised to the power of its position index (from right to left, starting at 0) and summing the results.

Example

For the hexadecimal number A1F:

  • F = 15 × 160 = 15
  • 1 = 1 × 161 = 16
  • A = 10 × 162 = 2560

Decimal result = 15 + 16 + 2560 = 2591
