How do you convert binary to hexadecimal?

Group bits into sets of four from the right (pad with leading zeros if needed). Each group maps to one hex digit 0–F.

1111₂ = F₁₆ = 15 in decimal.

Why use hex instead of long binary?

Hex is shorter and aligns with byte boundaries (two hex digits = one byte).

You can pad with leading zeros so the leftmost group has four bits before converting.
