The hex calculator performs addition, subtraction, multiplication, and division on hexadecimal (base-16) numbers. Enter two hex values, choose an operation, and see results in hex, decimal, binary, and octal.
Hexadecimal uses sixteen digits: 0 through 9 and A through F, where A equals 10 and F equals 15 in decimal. Carrying and borrowing work the same way as in decimal, except the base is 16 instead of 10.
Hex is popular in computing because each hex digit maps neatly to exactly four binary bits, making it a compact way to represent binary data such as memory addresses, colour codes, and MAC addresses.
Web colours are expressed as six-digit hex codes. Memory addresses in debuggers and low-level programming are shown in hex. File checksums and hash digests are typically displayed as hex strings.
Frequently asked questions
No. A through F and a through f represent the same values. Convention varies by context, but the calculator accepts either.
Hex is more compact. One hex digit replaces four binary digits, making large binary values much easier to read and type.
