Decimal to HEX
A Decimal to HEX (Hexadecimal) Tool is a simple and efficient online utility that helps you convert decimal (base-10) numbers into hexadecimal (base-16) format. This type of conversion is particularly useful for programmers, web developers, electronics engineers, and students who often work with hexadecimal representations of numbers in computer systems, memory addresses, or color codes.

This type of conversion is particularly useful for programmers, web developers, electronics engineers, and students who often work with hexadecimal representations of numbers in computer systems, memory addresses, or color codes.
How It Works
The tool takes a decimal number as input and converts it into its equivalent hexadecimal value using base conversion logic. In a hexadecimal system, numbers are represented using 16 symbols: 0-9
and A-F
, where:
-
A = 10
-
B = 11
-
C = 12
-
D = 13
-
E = 14
-
F = 15
For example:
-
Decimal
10
→ HexA
-
Decimal
255
→ HexFF
-
Decimal
4096
→ Hex1000
Key Features
-
✅ Instant Conversion: Enter a decimal number, and the HEX value appears instantly.
-
✅ User-Friendly Interface: Simple and clean design for fast results.
-
✅ Supports Large Numbers: Convert large decimal values without any lag.
-
✅ Copy to Clipboard: Easily copy the converted HEX value with one click.
-
✅ Free to Use: No registration or payment required.
Why Use Decimal to HEX Converter?
-
Web Design & Development: Hexadecimal values are used in HTML/CSS color codes (e.g.,
#FF5733
). -
Computer Programming: Many low-level programming languages use hex to reference memory locations.
-
Networking: IP addresses in IPv6 and MAC addresses use hex format.
-
Electronics & Microcontrollers: HEX values are used to program hardware devices like Arduino, PIC, or STM32.
Example Use Cases
Decimal | Hex |
---|---|
16 | 10 |
100 | 64 |
255 | FF |
1024 | 400 |
65535 | FFFF |
How to Use the Tool
-
Input: Type or paste the decimal number into the input field.
-
Convert: The tool automatically converts the value to hexadecimal.
-
Copy: Click the "Copy" button to use the HEX value elsewhere.
Decimal to HEX Formula (For Manual Conversion)
To convert a decimal number to hexadecimal manually:
-
Divide the decimal number by 16.
-
Write down the remainder (0–15).
-
Divide the quotient by 16 again and repeat until the quotient is 0.
-
The HEX value is the string of remainders read from bottom to top.
Example: Convert 156 to HEX
156 ÷ 16 = 9, remainder = 12 (C)
9 ÷ 16 = 0, remainder = 9
→ HEX = 9C
Conclusion
The Decimal to HEX Converter Tool is a handy solution for developers, students, and IT professionals who need fast and reliable base conversions. Whether you're debugging code, creating color palettes, or working with microcontrollers, this tool makes your job easier with just a few clicks.
