Whether you are a student, programmer, web developer, or computer science enthusiast, this free online tool provides a convenient way to convert base-10 numbers into base-16 values.
What Is the Decimal Number System?
The decimal number system is a positional numeral system with a base of 10.
It uses ten digits:
0, 1, 2, 3, 4, 5, 6, 7, 8, 9.
Each position represents a power of 10.
For example, the decimal number 245 can be expanded as:
2 × 100 = 200
4 × 10 = 40
5 × 1 = 5
The total value is 245.
Decimal is commonly used for everyday calculations, measurements, financial values, and numerical information.
What Is the Hexadecimal Number System?
The hexadecimal number system, also known as hex, is a positional numeral system with a base of 16.
It uses sixteen symbols:
Numbers: 0, 1, 2, 3, 4, 5, 6, 7, 8, 9
Letters: A, B, C, D, E, F
The letters represent decimal values from 10 to 15.
| Hexadecimal | Decimal |
|---|---|
| 0 | 0 |
| 1 | 1 |
| 2 | 2 |
| 3 | 3 |
| 4 | 4 |
| 5 | 5 |
| 6 | 6 |
| 7 | 7 |
| 8 | 8 |
| 9 | 9 |
| A | 10 |
| B | 11 |
| C | 12 |
| D | 13 |
| E | 14 |
| F | 15 |
Hexadecimal is useful because it represents large binary values using fewer characters.
How to Convert Decimal to Hexadecimal
One common method for converting a positive decimal integer into hexadecimal is repeated division by 16.
Follow these steps:
Divide the decimal number by 16.
Record the remainder.
Convert any remainder from 10 to 15 into its corresponding hexadecimal letter (A to F).
Divide the quotient by 16 again.
Continue until the quotient becomes 0.
Read the remainders from bottom to top.
The result is the hexadecimal representation of the original decimal number.
Decimal to Hex Conversion Examples
Example 1: Convert 255 to Hexadecimal
Start with the decimal number 255.
| Division | Quotient | Remainder |
|---|---|---|
| 255 ÷ 16 | 15 | 15 |
| 15 ÷ 16 | 0 | 15 |
The remainder 15 corresponds to F in hexadecimal.
Read the remainders from bottom to top:
255 (decimal) = FF (hexadecimal)
Example 2: Convert 100 to Hexadecimal
Start with 100.
| Division | Quotient | Remainder |
|---|---|---|
| 100 ÷ 16 | 6 | 4 |
| 6 ÷ 16 | 0 | 6 |
Read the remainders from bottom to top:
100 (decimal) = 64 (hexadecimal)
Example 3: Convert 4096 to Hexadecimal
Start with 4096.
| Division | Quotient | Remainder |
|---|---|---|
| 4096 ÷ 16 | 256 | 0 |
| 256 ÷ 16 | 16 | 0 |
| 16 ÷ 16 | 1 | 0 |
| 1 ÷ 16 | 0 | 1 |
Read the remainders from bottom to top:
4096 (decimal) = 1000 (hexadecimal)
Example 4: Convert 1234 to Hexadecimal
Divide the number repeatedly by 16:
| Division | Quotient | Remainder |
|---|---|---|
| 1234 ÷ 16 | 77 | 2 |
| 77 ÷ 16 | 4 | 13 |
| 4 ÷ 16 | 0 | 4 |
The remainder 13 corresponds to D.
Read the remainders from bottom to top:
1234 (decimal) = 4D2 (hexadecimal)

Decimal to Hexadecimal Conversion Formula
A hexadecimal number can be expanded into a sum of powers of 16.
For example, the hexadecimal number 2F represents:
2 × 16¹ = 32
F × 16⁰ = 15
Add the values:
32 + 15 = 47
Therefore:
2F (hexadecimal) = 47 (decimal)
This demonstrates how hexadecimal place values work.

2. Web Design and Color Codes
Hexadecimal notation is widely used in HTML and CSS to represent colors.
For example:
#FF0000 represents red.
#00FF00 represents green.
#0000FF represents blue.
#FFFFFF represents white.
#000000 represents black.
These color values use hexadecimal notation to represent red, green, and blue components.
3. Computer Memory
Hexadecimal makes long binary values easier to read when examining memory locations and data.
4. Digital Electronics
Hexadecimal is useful for representing binary values in a more compact format.
5. Networking
Hexadecimal notation appears in technical contexts such as hardware addresses and network-related data.
Decimal vs Binary vs Hexadecimal
These three number systems can represent the same numerical value using different bases.
| Feature | Decimal | Binary | Hexadecimal |
|---|---|---|---|
| Base | 10 | 2 | 16 |
| Digits | 0–9 | 0 and 1 | 0–9 and A–F |
| Example | 255 | 11111111 | FF |
| Common use | Everyday calculations | Digital systems | Programming and data representation |
One hexadecimal digit represents exactly four binary bits. This makes hexadecimal especially useful when working with binary data.
