Hexadecimal to Binary Conversion Calculator
Use this tool to convert hexadecimal numbers into binary. Perfect for students, engineers, and anyone working with different number systems.
Understanding Hexadecimal to Binary Conversion
What is Hexadecimal?
Hexadecimal is a base-16 number system that uses sixteen digits: 0-9 and A-F. It is often used in computing as a more human-friendly representation of binary numbers, as it is more compact and easier to read.
What is Binary?
Binary is a base-2 number system that uses only two digits: 0 and 1. It is the fundamental system for computers and digital electronics because it directly corresponds to the on/off states of a transistor in a computer's processor.
Why Convert Hexadecimal to Binary?
Hexadecimal is widely used in programming and digital electronics because it is a shorthand for binary. Each hexadecimal digit corresponds to exactly four binary digits (bits), making it easier to work with long binary values in a compact and readable format. Converting hexadecimal to binary allows for more detailed data manipulation at the bit level.
How Hexadecimal to Binary Conversion Works
The conversion from hexadecimal to binary involves converting each hexadecimal digit into its corresponding 4-bit binary equivalent.
For example, to convert the hexadecimal number 1F3 to binary:
- 1 →
0001 - F →
1111 - 3 →
0011
The binary representation of 1F3 is 000111110011.
Practical Examples
| Hexadecimal Number | Binary Equivalent |
|---|---|
| A | 1010 |
| F | 1111 |
| 3B | 00111011 |
| 7D2 | 011111010010 |
Frequently Asked Questions
What is the largest hexadecimal number I can input?
You can input very large hexadecimal numbers. The calculator will handle numbers as large as 64-bit or even higher, depending on your browser and device limitations.
Can I convert hexadecimal numbers with lowercase letters?
Yes! The calculator can handle both uppercase and lowercase letters in hexadecimal numbers. For example, a is the same as A.
Why is hexadecimal used in computing?
Hexadecimal is used in computing because it provides a more compact representation of binary numbers. Since each hexadecimal digit corresponds to four binary digits, it's much easier to work with than long strings of 1s and 0s. It is also used in color codes, memory addresses, and machine-level programming.
