Hex Calculator — Hexadecimal Arithmetic, Bitwise Logic & Number Conversions
The Hex Calculator performs arithmetic operations (addition, subtraction, multiplication, and division) directly in base-16 (hexadecimal) and converts values instantly between Hexadecimal, Decimal, Binary, and Octal number systems.
Hexadecimal Digits: 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, A (10), B (11), C (12), D (13), E (14), F (15).
Byte Representation: Each hexadecimal digit represents exactly 4 binary bits (a nibble). Two hex digits represent one 8-bit byte (0x00 to 0xFF, spanning 0 to 255 in decimal).
Hexadecimal notation is used across memory address referencing, assembly programming, network MAC addresses, IPv6 routing, and web CSS colour codes (e.g. #FFFFFF). To perform binary-only logic, switch to our Binary Calculator or general Scientific Calculator.
