Hex Calculator
Convert a decimal number to hexadecimal.
Worth Knowing
Hexadecimal uses sixteen digits — 0–9 then A–F — so a single hex digit represents values 0 through 15 and maps cleanly onto four binary bits. That tidy 4-bit correspondence is why programmers reach for hex constantly: colors like #FF8800, memory addresses, and byte values are all far more readable in hex than in long binary strings. Converting between decimal and hex is really just regrouping the same quantity, not changing its value.
