    Type hex values using digits 0–9 and letters A–F (case insensitive) into the input fields.

  2. 2

    Select an operation

    Choose from arithmetic operations (add, subtract, multiply, divide) or bitwise operations (AND, OR, XOR, NOT, shift).

  3. 3

    View multi-base results

Frequently Asked Questions

Why is hexadecimal used in programming?
Hexadecimal is compact and maps directly to binary — each hex digit represents exactly 4 bits. This makes it ideal for representing memory addresses, color codes, byte values, and CPU instructions.
What are bitwise operations used for?
Bitwise AND, OR, XOR, and NOT manipulate individual bits. They are used for low-level programming, setting/clearing flags, masking values, and optimizing performance-critical code.
How do I convert hex to decimal?
Multiply each hex digit by 16 raised to its position power and sum the results. For example, 0x1F = (1 × 16¹) + (15 × 16⁰) = 16 + 15 = 31.

About Hex Calculator
