Number System Converter tool by SmartCalcZone is an online base converter designed to help you switch between binary, decimal, octal, and hexadecimal formats easily. This converter is perfect for students, developers, and tech enthusiasts learning how different number systems work.
With this easy-to-use base conversion calculator now, you can perform accurate conversions between binary to decimal, decimal to hex, octal to binary, etc.
When you’re learning about computer logic, programming, or digital electronics, our number conversion tool provides both accuracy and simplicity for all users.
A number system is a way to represent numbers using a specific set of symbols and a base value. The base (or radix) tells you how many digits are available in that system.
For example, our everyday system is the decimal system (base 10), which uses ten digits: 0–9. Computers, however, use other systems such as binary (base 2), octal (base 8), and hexadecimal (base 16).
We are going to show conversions between decimal, binary, octal, and hexadecimal systems. It helps you understand how numbers look in each format.
| Decimal | Binary | Octal | Hexadecimal |
|---|---|---|---|
| 1 | 1 | 1 | 1 |
| 2 | 10 | 2 | 2 |
| 5 | 101 | 5 | 5 |
| 8 | 1000 | 10 | 8 |
| 10 | 1010 | 12 | A |
| 15 | 1111 | 17 | F |
| 16 | 10000 | 20 | 10 |
| 31 | 11111 | 37 | 1F |
| 63 | 111111 | 77 | 3F |
| 255 | 11111111 | 377 | FF |
The conversion tool works in two main steps:
For example, when you convert binary 1010 to decimal, it equals 10. Then converting 10 to hexadecimal gives you A. This two-step conversion process ensures maximum accuracy.
Apart from base conversions, SmartCalcZone also provides a converter that helps you switch between Indian number formatting
| Indian Number System | International Number System |
|---|---|
| 1,000 | 1 Thousand |
| 1,00,000 | 100 Thousand (1 Lakh) |
| 10,00,000 | 1 Million |
| 1,00,00,000 | 10 Million (1 Crore) |
| 1,00,00,00,000 | 1 Billion |
To convert binary 1010 to decimal:
Multiply each binary digit by 2 raised to its position value, starting from the right.
(1 × 2³) + (0 × 2²) + (1 × 2¹) + (0 × 2⁰) = 8 + 0 + 2 + 0 = 10
So, Binary 1010 = Decimal 10.
To convert decimal 255 to hexadecimal:
Divide 255 by 16. Quotient = 15, Remainder = 15 → which corresponds to F.
Hence, 255 in hexadecimal is FF.
A base converter helps you switch between different number systems like binary, decimal, octal, and hexadecimal. It’s used in mathematics, computer science, and electronics to simplify calculations and understand how computers process data.
This converter uses precise algorithms to ensure accuracy. It first converts every input into decimal (if it is not already decimal) and then converts it into the desired base, which guarantees consistent results.

Yes, it’s completely free with no hidden charges. You don’t need to create an account or download any software.
Currently, this tool supports the most commonly used bases — binary (2), octal (8), decimal (10), and hexadecimal (16). Support for custom base systems may be added in future updates.
The Indian number system uses terms like lakh (1,00,000) and crore (1,00,00,000), while the international system uses thousand (1,000) and million (1,000,000). Our converter helps you easily convert between these two formats.
Anyone! It’s designed for students learning number systems, software developers dealing with hexadecimal color codes or binary logic, electronics engineers working with digital circuits, and anyone interested in understanding number formats better.
