The Hex to Decimal Converter is a tool designed to convert a given hexadecimal (hex) number into its corresponding decimal (base-10) value. Hexadecimal is a base-16 number system widely used in computing and digital electronics for its compact representation of binary data. The decimal system, on the other hand, is the standard number system used in everyday life, based on powers of 10.

   - Hexadecimal Number: The user provides a hexadecimal number (e.g., "1A3", "FF", "A7B9"). Hexadecimal uses the digits "0-9" and the letters "A-F" to represent values 0 through 15.

   - Decimal Number: The tool converts the given hexadecimal value into its equivalent decimal (base-10) number and displays it.

To convert a hexadecimal number into decimal, the following steps are performed:

1. Hexadecimal to Decimal Conversion:

   - Each digit in a hexadecimal number corresponds to a power of 16, starting from the rightmost digit, which is the least significant digit.

   - The value of each hex digit is multiplied by 16 raised to the power of its position (starting from position 0).

   - The results of these multiplications are then summed together to produce the decimal value.

- Hexadecimal "1A3":

  - The digits are "1", "A", and "3".

  - In decimal, "A" is equal to "10".

  - The calculation is:  

    (1 * 16^2) + (A * 16^1) + (3 * 16^0)

    = (1 * 256) + (10 * 16) + (3 * 1)

    = 256 + 160 + 3

    = 419

   So, "1A3" in hexadecimal is equal to 419 in decimal.

Let’s take the input hexadecimal number "F5" as an example:

1. Hexadecimal to Decimal Conversion:

   - The digits are "F" and "5".

   - "F" in hexadecimal equals "15" in decimal.

   

   The calculation is:

   (F * 16^1) + (5 * 16^0) = (15 * 16) + (5 * 1)

   = 240 + 5 = 245

   So, the hexadecimal number "F5" is equal to 245 in decimal.
