Conversor Hexadecimal Online Grátis
Hex arithmetic and conversion between hex, decimal, binary and octal
The Hexadecimal Calculator performs addition, subtraction, multiplication, and division directly in base-16, while also converting values to decimal, binary, and octal instantly. Programmers working with memory addresses, color codes, bitmasks, and hardware registers use it to skip error-prone manual conversion. Results update as you type, showing all four number bases side by side.
Frequently Asked Questions
Sobre Esta Calculadora
Hexadecimal (base-16) is the native language of low-level computing. Memory addresses in debuggers, HTML/CSS color values (#FF5733), Unix file permissions, and CPU register dumps are all expressed in hex because it maps cleanly to binary nibbles — four binary digits equal exactly one hex digit.
Doing hex arithmetic by hand means mentally converting to decimal, performing the operation, then converting back — a process prone to mistakes that wastes time in debugging sessions. This calculator handles the full round-trip: enter values in any base and it computes the result in all four simultaneously.
The tool supports both unsigned hex integers and the common operations needed for bitmask manipulation, bitwise flag checking, and address offset calculations. Developers debugging embedded systems, writing assembly, or inspecting packet captures will find it especially useful alongside the Number Base Converter.

Exemplo Resolvido
Adding two hex values used as bitmask flags
Entradas:
- First operand: 0x3A (binary: 0011 1010, decimal: 58)
- Second operand: 0x15 (binary: 0001 0101, decimal: 21)
- Operation: Addition
Passo a Passo:
- Decimal equivalent: 58 + 21 = 79
- Convert 79 to hex: 79 ÷ 16 = 4 remainder 15 (F) → 4F
- Hex result: 0x4F
- Binary check: 0011 1010 + 0001 0101 = 0100 1111 = 0x4F ✓
