Hex to Decimal Converter
Convert hexadecimal (base 16) numbers to decimal (base 10) instantly, updating live as you type. Hexadecimal uses the digits 0 to 9 plus the letters A to F to pack four bits into each character, which is why it shows up everywhere in programming, color codes, memory addresses, and MAC addresses. Converting it in your head means multiplying by powers of sixteen, which is awkward, so this tool sums the place values for you. Type a hex value, with or without a leading 0x, in upper or lower case, and the decimal equivalent appears immediately, with a clear flag if you enter a character that is not a valid hex digit. Everything is computed in your browser, so it is fast, keeps your input private, and works offline after loading.
