Digits 0-9 and letters A-F allowed
Hexadecimal uses digits 0-9 and letters A-F, providing a compact representation of binary data used extensively in programming and web development.
Decimal uses digits 0-9 and is the standard number system for everyday mathematics, business calculations, and human-readable numbers.
Convert CSS hex color codes to RGB decimal values for precise color manipulation, analysis, and understanding color composition.
Essential for debugging, understanding memory layouts, and translating programmer-friendly hex addresses to human-readable decimal values.
Important for analyzing binary files, understanding data structures, and converting hex dump output to decimal for calculations.
Used for interpreting system logs, error codes, and converting hex values from various system tools to decimal for analysis.
Input your hexadecimal number using digits 0-9 and letters A-F.
System multiplies each digit by its power of 16 and sums the results.
Copy your decimal result for use in calculations or applications.
Multiply each hex digit by its corresponding power of 16 and sum the results. A=10, B=11, C=12, D=13, E=14, F=15. For example, hex FF = (15×16¹) + (15×16⁰) = 240 + 15 = 255 decimal.
Hexadecimal uses digits 0-9 and letters A-F (case insensitive). A=10, B=11, C=12, D=13, E=14, F=15. Our converter accepts both uppercase and lowercase letters.
Converting hex to decimal is essential for understanding memory addresses, color values, debugging output, and translating programmer-friendly hex notation into human-readable numbers.
Our converter automatically handles hex numbers with or without the 0x prefix. Simply enter FF or 0xFF - both will convert correctly to decimal 255.
Yes, hexadecimal to decimal conversion is mathematically exact with no precision loss. Both systems represent the same integer values, just in different bases (16 vs 10).
