Convert binary to hexadecimal. Group bits in sets of 4 for quick conversion. Whether you're solving coding interview problems or studying for exams, understanding how to convert binary to hexadecimal is essential.

Conversion Logic:

Group binary digits into groups of 4 (right to left), then convert each group to its hex digit (0-F).

This is a fundamental skill tested in coding interviews, competitive programming, and CS theory exams.

Example 1

Input: 11111111

Output: FF

Explanation: 1111=F, 1111=F → FF (decimal 255)

Example 2

Input: 10101011

Output: AB

Explanation: 1010=A, 1011=B → AB

Example 3

Input: 00010000

Output: 10

Explanation: 0001=1, 0000=0 → 10 (decimal 16)

Test your understanding with these exercises:

1.Convert 5 different values using the method above

2.Implement the conversion algorithm in your preferred language

3.Solve related problems on W Code to build speed

Interview tip: Be ready to explain the conversion process step-by-step on a whiteboard.

python
def binary_to_hex(binary_str: str) -> str:
    decimal_value = int(binary_str, 2)
    return hex(decimal_value)[2:].upper()

Group binary digits into groups of 4 (right to left), then convert each group to its hex digit (0-F).

Yes, number system conversions are common in aptitude rounds and bit manipulation problems.

Related: binary-to-decimal, hex-to-binary, decimal-to-hex. Understanding these together builds a complete foundation.
