Decimal to Hexadecimal Converter
Decimal to Hexadecimal Converter
Enter a whole decimal number to instantly see its hexadecimal equivalent — commonly used for color codes, memory addresses, and compact byte representations.
The conversion method mirrors decimal-to-binary but divides by 16 instead of 2, converting any remainder from 10-15 into its corresponding letter A-F since hexadecimal needs sixteen distinct digit symbols — 255 converts cleanly to FF, the maximum value a single byte (two hex digits) can represent. Hexadecimal is especially common in web design because color codes like #FF5733 pack the red, green, and blue channel values into exactly two hex digits each, a far more compact notation than writing out the equivalent decimal or binary values.
- Method: repeatedly divide the number by 16, converting remainders 10-15 into letters A-F.
- Example: 255 ÷ 16 = 15 r15 → 15 becomes F, remainder 15 becomes F → FF.
- Common use: web colors like #FF5733 use pairs of hex digits (00-FF) for red, green, and blue values.
What is 4096 in hexadecimal?
1000 — since 16³ = 4096.
Why does hexadecimal use letters?
Base 16 needs 16 distinct digits, so after 0-9 it continues with A (10) through F (15).
