Why base 2 and base 16 pair naturally

Each hexadecimal digit represents exactly 4 binary bits, since 16 = 2⁴ — which is why hex is used throughout computing as compact shorthand for binary. Converting between them is really just regrouping bits in sets of four, not a separate calculation.

A leading-zero mistake to avoid

Dropping leading zeros in a binary group can misalign a conversion — 0011 and 11 represent the same value, but grouping bits without padding to full 4-bit groups can shift everything after it. Pad binary numbers to a multiple of 4 bits before converting to hex.
