Working with different number systems is a fundamental skill in computer science, mathematics, and digital electronics. The Number Base Converter is a simple and efficient online tool designed to convert numbers between four commonly used bases: binary, octal, decimal, and hexadecimal.
Whether you are a student learning about base systems, a programmer handling low-level data, or someone exploring how numbers work in computing, this tool can help streamline your process.
A Number Base Converter allows users to input a number in one base and instantly see its equivalent in other number systems. For example, the decimal number 15 can be represented as:
Binary: 1111
Octal: 17
Hexadecimal: F
This converter supports the following bases:
Binary (Base 2)
Octal (Base 8)
Decimal (Base 10)
Hexadecimal (Base 16)
Enter the number you want to convert into the input field.
Select the base of the input number from the dropdown menu.
Click the “Convert” button.
View the converted results in all other number bases.
Use the “Clear” button to reset the fields and start a new conversion.
All outputs are read-only, allowing easy copy and paste functionality.
Below is a brief explanation of each number system the converter supports:
Uses only two digits: 0 and 1
Common in digital systems and computing
Example: 1010 (binary) = 10 (decimal)
Uses digits 0 through 7
Occasionally used in computing, especially in Unix-based systems
Example: 17 (octal) = 15 (decimal)
Standard number system used in daily life
Uses digits 0 through 9
Example: 255 (decimal) = FF (hexadecimal)
Uses digits 0–9 and letters A–F (A = 10, B = 11, …, F = 15)
Widely used in programming, memory addressing, and web color codes
Example: 1A (hex) = 26 (decimal)
This converter is useful for a wide range of users, including:
Students learning number systems or computer science fundamentals
Software developers working with low-level or embedded code
Engineers and technicians handling digital logic circuits
Web developers using hexadecimal color values
Educators teaching base conversion in classrooms
Fast and accurate base conversion
Clean, user-friendly interface
No internet required after loading the tool
Educational definitions for all supported bases
Responsive design suitable for both desktop and mobile use
The built-in base definitions section provides a quick reference to understand each number system, making it easier to learn and apply the concepts during actual conversions.
The Number Base Converter is a practical and easy-to-use tool for converting numbers between binary, octal, decimal, and hexadecimal formats. Whether for learning, teaching, or professional use, it provides a quick and reliable solution for working with different numeral systems.
Use the converter above to begin converting numbers in just a few steps. Whether you’re dealing with a binary value or a hexadecimal code, this tool helps you work faster and more accurately.
