How to Convert Hex to Binary
Hexadecimal and binary numbers are foundational to computing systems, networking, and software engineering. Converting from a hexadecimal to a binary number is very common because base 16 offers a clean way to express four base 2 digits for each base 16 used, making it much easier to read.
Binary numbers, or base 2 numbers, consist of two digits: 0 and 1. Hexadecimal numbers, or base 16 numbers, consist of 16 digits: 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, a, b, c, d, e & f.
To convert hex to binary, convert each digit to the equivalent binary number. Each hex digit is equal to four binary digits or bits, also referred to as a nibble.
Hex Character Nibble Values
This chart shows the binary nibble value for each hexadecimal digit.
Hexadecimal Digit | Binary Nibble |
---|---|
0 | 0000 |
1 | 0001 |
2 | 0010 |
3 | 0011 |
4 | 0100 |
5 | 0101 |
6 | 0110 |
7 | 0111 |
8 | 1000 |
9 | 1001 |
a | 1010 |
b | 1011 |
c | 1100 |
d | 1101 |
e | 1110 |
f | 1111 |
After converting each hex digit to a nibble, place the nibbles together to get the final number.

For example, let’s convert f3b716 to binary.
f16 = 11112
316 = 00112
b16 = 10112
716 = 01112
Putting it all together the final binary value is:
1111 0011 1011 0111
Removing the spaces we end up with:
11110011101101112
