Hex Calculator: The Complete Guide
Do math in hexadecimal. Enter two hex numbers and an operation — arithmetic or bitwise — to get the result in hex, with its decimal and binary equivalents.
Who the Hex Calculator is for
Developers and students performing hexadecimal arithmetic and bitwise operations.
How to use the Hex Calculator
- Type your values into the fields above — pick your currency or units where the calculator offers them.
- Results update automatically as you type; there's no submit button and nothing is sent to a server.
- Adjust any input to compare scenarios, then copy the result with a single click.
How it works
Both hex inputs are parsed to integers, the chosen operation (+, −, ×, ÷, AND, OR, XOR) is applied, and the result is converted back to hexadecimal, decimal, and binary.
Features
- Arithmetic & bitwise
- Hex, decimal & binary output
- AND, OR, XOR
- Runs locally
Why hexadecimal?
Hexadecimal (base 16) is compact and maps neatly to binary — each hex digit is exactly four bits — which is why it's used for colours, memory addresses, and byte values. This calculator performs arithmetic and bitwise operations on hex numbers and shows the result across hex, decimal, and binary.
