    FAQ

    What is hexadecimal used for?

    Hexadecimal is widely used in programming and computing to represent memory addresses, CSS color codes (like #FF5733), and binary data in a more compact, human-readable form — each hex digit stands for exactly 4 bits.

    How do you convert a decimal number to hexadecimal?

    Divide the decimal number by 16 repeatedly, writing down each remainder as a hex digit (0-9 stay the same, 10-15 become A-F), then read the remainders from last to first. For example, dividing 1,000 by 16 repeatedly gives remainders that read back as 3E8.

    Is 0 a valid hexadecimal digit?

    Yes. 0 is a valid hex digit and a valid decimal number to convert — decimal 0 converts to hexadecimal 0.
