The Hexadecimal to Decimal Converter is a tool that helps you convert numbers from Hexadecimal (base 16) format to Decimal (base 10) format. Hexadecimal is often used in computing and digital systems because it provides a more compact representation of binary data, while Decimal is the number system most commonly used by humans.

What Is Hexadecimal?

• Hexadecimal (Base 16) is a numeral system that uses 16 digits to represent values: 0-9 (representing values 0 to 9) and A-F (representing values 10 to 15).
• Each digit in a hexadecimal number represents a power of 16.

For example, the hexadecimal number 2F3 is made up of three digits: 2, F, and 3. Each digit corresponds to a power of 16:

• The 2 is in the 16^2 (256s) place.
• The F (which equals 15 in decimal) is in the 16^1 (16s) place.
• The 3 is in the 16^0 (1s) place.

What Is Decimal?

• Decimal (Base 10) is the standard numbering system used in everyday life. It uses ten digits: 0-9.
• Each digit in a decimal number represents a power of 10.

For example, in the decimal number 245:

• The 2 is in the 10^2 (hundreds) place.
• The 4 is in the 10^1 (tens) place.
• The 5 is in the 10^0 (ones) place.

How to Convert Hexadecimal to Decimal

To convert a hexadecimal number to decimal, follow these steps:

1. Start from the rightmost digit (the least significant digit) and assign it a place value that starts at 16^0 (1).
2. Move left, increasing the exponent by 1 for each place.
3. Multiply each digit in the hexadecimal number by the corresponding power of 16.
4. Sum the results to get the final decimal value.

Example Conversion: Hexadecimal to Decimal

Let’s convert the hexadecimal number 2F3 to decimal:

• 2F3 in hexadecimal means:
  • 2 is in the 16^2 (256s) place.
  • F (which equals 15) is in the 16^1 (16s) place.
  • 3 is in the 16^0 (1s) place.

Now, multiply each digit by its corresponding power of 16:

• 2 × 16^2 = 2 × 256 = 512
• F (15) × 16^1 = 15 × 16 = 240
• 3 × 16^0 = 3 × 1 = 3

Now, add these values together:

• 512 + 240 + 3 = 755

So, the hexadecimal number 2F3 is equal to the decimal number 755.

Hexadecimal to Decimal Conversion Example

Let’s take a more detailed example and convert a larger hexadecimal number to decimal.

Hexadecimal: A1B

1. Break the number down:
   • A is in the 16^2 (256s) place.
   • 1 is in the 16^1 (16s) place.
   • B (which equals 11 in decimal) is in the 16^0 (1s) place.
2. Convert each digit:
   • A × 16^2 = 10 × 256 = 2560
   • 1 × 16^1 = 1 × 16 = 16
   • B × 16^0 = 11 × 1 = 11
3. Add up the results:
   • 2560 + 16 + 11 = 2587

So, the hexadecimal number A1B equals 2587 in decimal.
