Quickly convert decimal numbers to accurate hexadecimal values without any manual calculation.
A decimal to hex converter is an online tool that converts decimal numbers (base 10) into hexadecimal numbers (base 16). Decimal is the most common number system used in everyday life, while hexadecimal is widely used in digital electronics, programming, microcontrollers, networking, and cybersecurity. This tool makes hexadecimal conversion simple, fast, and accurate without needing any manual calculation.
The hexadecimal number system is extremely important in computing and digital systems. It is compact, easy to read, and ideal for representing binary data. Programmers, network engineers, developers, and hardware professionals regularly use hexadecimal numbers to work with memory addresses, color codes, machine-level instructions, MAC addresses, and assembly language.
Decimal numbers use base 10 and include digits from 0 to 9. Hexadecimal uses base 16 and includes digits from 0 to 9 and letters from A to F. To convert decimal to hexadecimal, the number is repeatedly divided by 16, and the remainders are used to form the hexadecimal value. Our online tool automatically performs this calculation for you.
| Decimal | Hexadecimal |
|---|---|
| 5 | 5 |
| 10 | A |
| 15 | F |
| 16 | 10 |
| 255 | FF |
| 4095 | FFF |
Decimal to Hex formula:
Divide the decimal number by 16 → Take the remainder → Convert remainder to hex → Repeat until quotient is 0.
Convert 255 to hexadecimal:
Final Answer = FF
