How to Convert Binary to Hexadecimal

Hexadecimal (base-16) uses digits 0–9 and A–F. Every 4 binary digits (bits) map directly to one hexadecimal digit. To convert, split binary into groups of four (padding with zeros if needed), then map each group to hex.

Why It Matters

Understanding this conversion is crucial in computing—especially in programming, networking, and digital systems—where hex gives a compact, human-readable form of binary data.
