Base Converter

The Base Converter translates numbers between binary, octal, decimal and hexadecimal. Type a value, choose the source and target bases, and the equivalent representation appears at once. It is built for programmers, students and anyone working with different number systems.

How to use this tool

1. Enter the number you want to convert.
2. Select the source base (binary, octal, decimal or hexadecimal).
3. Select the target base you want to convert to.
4. Click convert to see the result.

When to use this tool

• Checking color codes or memory addresses in different bases.
• Learning number systems in computer science courses.
• Verifying binary output from logic circuits.
• Converting between hex and decimal for configuration files.

Practical examples

The decimal value 255 becomes FF in hexadecimal and 11111111 in binary. Entering 255 with decimal as the source and hexadecimal as the target returns FF, which is the familiar upper bound of an 8-bit byte.

Tips for accurate results

• Make sure digits are valid for the chosen source base, for example only 0 and 1 for binary.
• Hexadecimal letters can be upper or lower case, both are accepted.
• Double-check large values across bases to avoid copy mistakes.
