Base-16 to Decimal Converter

Ever found yourself staring at a hexadecimal number like "1A" or "FF" and thinking, "What on earth does this mean in plain English?" You're not alone! Hexadecimal (or base-16) numbers are everywhere—from coding to color codes—but they can feel like a secret language. Luckily, this Base-16 to Decimal Converter is here to save the day. Simply type in your hex number, hit convert, and voilà—you’ve got the decimal equivalent faster than you can say "math magic." Whether you're debugging code, designing graphics, or just curious, this tool makes converting hex to decimal a breeze. Say goodbye to head-scratching and hello to effortless number crunching!

Enter a hexadecimal (base-16) number to convert it to its decimal (base-10) equivalent.

Invalid hexadecimal input. Please enter a valid base-16 number.

This tool is for educational and practical purposes. No external APIs or libraries are used.

Here's how the magic happens: the tool takes your hexadecimal input (like "1A" or "3E7") and translates it into its decimal (base-10) counterpart. Hexadecimal numbers use digits 0-9 and letters A-F, where A = 10, B = 11, and so on up to F = 15. The tool multiplies each digit by 16 raised to the power of its position (starting from the right) and adds them all together. For example:

Example: Converting "1A" to Decimal

1 * 161 + A (10) * 160 = 16 + 10 = 26

To make it even easier, here's a quick reference table for some common hexadecimal to decimal conversions:
