Decimal (base-10) is the number system we use every day. Hexadecimal (base-16), often shortened to "hex," is widely used in computing because it's a more human-friendly way to represent binary-coded values.

Why Convert Between Them?

• Color Codes: Hex is used to define colors in web development (e.g., `#FFFFFF` for white).
• Memory Addresses: Debuggers and memory dumps often show memory locations in hex.
• File Inspection: When inspecting the raw bytes of a file, a hex editor provides a compact view of the data.

How It Works

This tool provides a simple way to convert numbers between the two systems. A decimal number is converted to hex by repeatedly dividing by 16 and recording the remainders. A hex number is converted to decimal by multiplying each digit by the appropriate power of 16 and summing the results.
