Convert binary numbers to decimal and vice versa. Free binary converter for computer science and digital electronics.
The Binary to Decimal Converter is an essential utility for anyone who needs quick, accurate calculations without installing software. In 2026, as remote work and digital workflows dominate, having instant access to reliable calculation tools in your browser saves time and eliminates errors.
Whether you're a student verifying homework, a professional preparing reports, or someone managing personal finances, our tool provides instant results with zero learning curve. Built with privacy-first technology, all calculations happen locally in your browser→your data never leaves your device.
Binary uses only two digits — 0 and 1. Each position represents a power of 2, starting from 2â° on the right. To convert binary to decimal, multiply each digit by its positional value and add them up: 1011 = 8 + 0 + 2 + 1 = 11. This converter does that arithmetic instantly and also shows the step-by-step breakdown so you can verify the result.
Manual conversion is error-prone on numbers longer than 8 bits. Pasting a value here takes less time than working it out by hand, and the breakdown makes it useful for learning the method, not just getting the answer.
