Multiply each bit by 2 raised to its position (counting from right, starting at 0), then add them up. Example: 1101 = 1×8 + 1×4 + 0×2 + 1×1 = 13.

Each hex digit represents exactly 4 bits (a nibble), so a byte is always exactly 2 hex digits. This makes hex a compact, human-readable representation of binary data — much shorter than writing out all the binary digits. Used extensively in memory addresses, color codes, and binary protocols.

A bit is a single binary digit (0 or 1). A nibble is 4 bits (one hex digit). A byte is 8 bits (two hex digits, values 0–255). A word is typically 16 or 32 bits depending on the architecture.
