Decimal to Hexadecimal

What is the Decimal to Hexadecimal Converter?

This tool converts decimal numbers (base-10) to hexadecimal (base-16), the preferred format for many computing applications.

Why Convert Decimal to Hex?

Hexadecimal is widely used in:

• Web design — creating color codes (#RGB)
• Programming — memory addresses, byte values
• Hardware — MAC addresses, device IDs
• Cryptography — hash representations

The Conversion

Divide by 16 repeatedly and convert remainders (10=A, 11=B, 12=C, 13=D, 14=E, 15=F).

Example: 255 = 15×16 + 15 → FF

How to Use

1. Enter decimal number — type any positive integer
2. View hex result — appears in uppercase (A-F)
3. Copy for use — add 0x prefix for code, # for CSS

Color Code Examples

• 255, 0, 0 → FF0000 (Red)
• 0, 255, 0 → 00FF00 (Green)
• 0, 0, 255 → 0000FF (Blue)
• 255, 255, 255 → FFFFFF (White)

Grouping

Results are grouped in pairs for readability (e.g., DE AD BE EF).
