How to Convert Decimal to Hexadecimal
Hexadecimal is base-16 and uses digits 0–9 and A–F. To convert, divide your decimal number by 16 repeatedly, recording remainders. Read remainders bottom-to-top for the hexadecimal value.
Example: Convert 255 to Hex
- 255 ÷ 16 = 15 remainder 15 → F
- 15 ÷ 16 = 0 remainder 15 → F
Decimal 255 = Hexadecimal FF
Why This Matters
Hexadecimal abbreviates long binary values in programming, architecture, networking, and more—making it crucial for readability and efficiency.
