Binary Calculator: The Complete Guide

Do math in binary. Enter two binary numbers and an operation — arithmetic or bitwise — to get the result in binary, with its decimal and hexadecimal equivalents.

Who the Binary Calculator is for

Students and developers performing binary arithmetic and bitwise operations.

How to use the Binary Calculator

  1. Type your values into the fields above — pick your currency or units where the calculator offers them.
  2. Results update automatically as you type; there's no submit button and nothing is sent to a server.
  3. Adjust any input to compare scenarios, then copy the result with a single click.

How it works

Both binary inputs are parsed to integers, the chosen operation (+, −, ×, ÷, AND, OR, XOR) is applied, and the result is converted back to binary, decimal, and hexadecimal.

Features

  • Arithmetic & bitwise
  • Binary, decimal & hex output
  • AND, OR, XOR
  • Runs locally

Working in binary

Binary is the base-2 number system computers use, with only 0s and 1s. This calculator handles both ordinary arithmetic and bitwise operations (AND, OR, XOR) on binary values, and shows the answer in binary, decimal, and hex so you can cross-check across number systems.

Frequently Asked Questions

What's the difference between add and bitwise OR?

Addition carries between columns; bitwise OR sets each bit to 1 if either input has a 1 there, with no carrying. They give different results.

Does division round?

Yes — binary division here returns the integer (floor) quotient, matching typical integer arithmetic.

Is this calculator free and private?

Yes. It's completely free with no signup, and every calculation runs locally in your browser, so your numbers never leave your device.
