Base Converter
Online base conversion tool supporting binary, octal, decimal, hexadecimal, and custom base (2-36) conversions. Supports big number calculations.
Usage
Common Bases
Binary: base 2, uses 0/1, the internal data storage format of computers; Octal: base 8, uses 0-7, commonly used for Unix file permissions; Decimal: base 10, the everyday number system; Hexadecimal: base 16, uses 0-9 and A-F, commonly used for color codes and memory addresses.
Steps
1. Enter a value in any base box and the others update automatically; 2. The custom base section supports bases 2-36, entering a value triggers auto-sync; 3. Changing the custom base recalculates from the decimal value; 4. Click "Copy" next to each box to copy its content.
Notes
This tool is based on bignumber.js, supporting arbitrary-precision big number conversion; custom base range supports 2-36; invalid characters do not trigger updates; hexadecimal output is automatically uppercase.
