Hexadecimal to Binary Calculator
Hexadecimal (Base-16) and Binary (Base-2) are the two most common numeral systems used in computer architecture, memory addressing, and low-level programming. Our Hex to Binary Converter allows developers to quickly and accurately translate hex values into their raw binary equivalents.
How the Conversion Works
The hexadecimal system uses 16 symbols: 0-9 and A-F. Because 16 is a power of 2 (2^4), every single hexadecimal digit maps perfectly to exactly four binary digits (called a nibble). For example:
- Hex
0= Binary0000 - Hex
9= Binary1001 - Hex
A= Binary1010 - Hex
F= Binary1111
To convert a larger hex string like 2F, you simply combine the binary values: 2 (0010) and F (1111) becomes 00101111.
