How to Convert Hexadecimal to Decimal
Method
Hexadecimal (base-16) uses digits 0-9 and letters A-F (where A=10, B=11, C=12, D=13, E=14, F=15). Enter the numeric value of each hex digit (0-15).
Decimal = d3×4096 + d2×256 + d1×16 + d0×1
For example, hex FF (enter 15, 15): 15×16 + 15×1 = 240 + 15 = 255.
