Hex → Binary Converter
Enter a hexadecimal number (e.g., A3) to convert to binary.
This Hex to Binary Converter tool will let users input a hexadecimal number (e.g., A3) and instantly see the equivalent binary value.
Hex to Binary Converter (Hexadecimal to Binary Calculator)
A Hex to Binary Converter is an online tool that converts hexadecimal (base-16) numbers into binary (base-2) format instantly. Users simply enter a hex value—such as A3—and the tool immediately displays the correct binary equivalent.
This conversion is commonly used in computer science, programming, networking, embedded systems, and digital electronics, where hexadecimal values often need to be translated into raw binary data.
Conversion Reference
- Hexadecimal (Hex) → Base-16
- Binary → Base-2
Example:
Hexadecimal: A
Binary: 1010
What Is a Hexadecimal Number System?
The hexadecimal system is a base-16 number system that uses:
- Numbers: 0–9
- Letters: A–F
| Hex | Decimal |
|---|---|
| A | 10 |
| B | 11 |
| C | 12 |
| D | 13 |
| E | 14 |
| F | 15 |
Hexadecimal is widely used because it represents long binary numbers in a shorter and more readable form.
What Is a Binary Number System?
The binary system is a base-2 number system that uses only two digits:
0 and 1
Computers rely on binary because hardware circuits naturally operate in two states: on (1) and off (0).
Hex to Binary Conversion Rule
The core rule is simple:
Each hexadecimal digit equals exactly 4 binary digits
This makes hex-to-binary conversion fast and reliable.
