Binary to Decimal Converter

Binary to Decimal Converter · displays power-of-2 bitwise weights · signed signed bit conversions

How it works
Convert in three steps

1. Enter the binary text

Type or paste your base-2 string (only using 0s and 1s) into the input field.

2. Check the conversion

The tool reads the binary code and calculates the equivalent base-10 value.

3. Copy the decimal

Save the resulting decimal number to your clipboard for your calculations.

FAQ
Common questions
This specific tool is optimized for integer binary conversions and does not support decimal points or fractional parts in the binary input. If you enter standard floating-point binary strings, the tool will trigger a format validation warning.
The tool processes standard unsigned binary integers. If you need to convert signed binary numbers (such as two complement notation), you should convert them manually using standard bitwise inversion or use advanced programming scripts.
To maintain mathematical precision inside the browser, inputs are limited to 53-bit binary strings (yielding decimals up to 9 quadrillion). Exceeding this length can result in minor precision rounding errors due to browser math limitations.
No, all calculations are executed client-side inside your browser session. None of the binary codes, decimal results, or user search histories are sent to external databases, keeping your data private.
