Decimal to HEX Converter Online

Use our free and fast Decimal to HEX Converter to convert decimal numbers (base-10) into hexadecimal (base-16) values instantly. Whether you're a developer working on low-level applications, a student studying number systems, or a tech enthusiast, this tool simplifies decimal to hexadecimal conversion.

What is a Decimal?

The decimal system is the standard number system used in everyday life. It is a base-10 system, meaning it uses 10 digits (0 through 9). Most people use decimal notation without even realizing it, as it's the foundation for nearly all arithmetic operations we perform daily.

What is Hexadecimal (HEX)?

Hexadecimal is a base-16 number system that uses sixteen digits: 0–9 and A–F. The letters A to F represent values from 10 to 15. HEX is widely used in computer science and digital electronics because it maps neatly to binary numbers (four binary digits = one hex digit).

How to Convert Decimal to HEX?

To convert a decimal number to hexadecimal, divide the number by 16 repeatedly and write down the remainder. Then reverse the sequence of remainders to get the hexadecimal equivalent.

Formula for Decimal to HEX Conversion:

Step 1: Divide the decimal number by 16.
Step 2: Record the remainder.
Step 3: Divide the result of Step 1 again by 16.
Step 4: Repeat until the result is 0.
Step 5: Write the remainders in reverse order.

Example:

Input: 2500
Step 1: 2500 ÷ 16 = 156, remainder = 4
Step 2: 156 ÷ 16 = 9, remainder = 12 (which is C in HEX)
Step 3: 9 ÷ 16 = 0, remainder = 9

Output (in reverse): 9C4
