Hex Calculator

Perform arithmetic and bitwise computations in base-16 with automatic decimal and binary conversions.

= 31 (decimal) = 11111 (binary)

= 10 (decimal) = 1010 (binary)

Result

0x29

= 41 (decimal) = 101001 (binary)

How to Use the Hex Calculator

  1. Enter valid hexadecimal characters (0-9, A-F) in Hex A.
  2. Choose an operation (+, -, ×, AND, OR, XOR).
  3. Enter your second hexadecimal operand in Hex B.
  4. View the output in Hex (0x...), Decimal, and Binary format.

Formulas & Principles

Hex addition and subtraction operate in base-16 with values 0-9 and A-F (10-15).

Conversion to decimal: multiply digit values by powers of 16.

Conversion to binary: map each hex digit to its corresponding 4-bit nibble.

Frequently Asked Questions

What is hexadecimal representation?

Hexadecimal is a base-16 numbering system that uses 16 symbols: 0-9 for values zero through nine, and A-F for values ten through fifteen.

Why do programmers use hexadecimal?

Hex simplifies binary code: exactly 4 binary bits (a nibble) represent 1 hexadecimal digit, making 8-bit bytes cleanly readable as two hex characters (e.g. 11111111 = 0xFF).

How do you convert Hex to Decimal?

Multiply each hex digit by 16 raised to its position power from the right (0, 1, 2...) and sum the results (e.g. 1F = 1×16¹ + 15×16⁰ = 31).
