What is Hexadecimal to Decimal Conversion?

Hexadecimal to decimal conversion transforms base-16 numbers into base-10 numbers. Hex digits 0-9 keep their values, while A=10, B=11, C=12, D=13, E=14, F=15. Multiply each digit by 16 raised to its position power and sum all results.

How to Convert Hex to Decimal Step-by-Step

1. Write the hex number and assign position values (powers of 16, right to left). 2. Convert each hex digit to its decimal value (A=10...F=15). 3. Multiply each digit by 16^position. 4. Add all products. Example: FF = F×16¹ + F×16⁰ = 15×16 + 15×1 = 240+15 = 255 Example: 1A = 1×16 + 10×1 = 26
