Add, subtract, multiply, divide, or apply bitwise operations to two hexadecimal numbers and see the result in hex, decimal, binary, and octal.

About Hex Calculator

Hexadecimal is the base-16 number system, using the digits 0 to 9 and the letters A to F for the values 10 to 15. This calculator reads two hexadecimal integers without a 0x prefix, applies arithmetic or a bitwise AND, OR, or XOR with exact big-integer arithmetic, and shows the result in binary, decimal, hexadecimal, and octal. Division discards the remainder. Letters can be upper or lower case; fractions are not supported.

Questions about Hex Calculator

What do AND, OR, and XOR do?

They compare two numbers bit by bit. AND gives 1 where both bits are 1, OR where at least one is 1, and XOR where exactly one is 1. For example, FF AND 1A is 1A.
