Decimal to Hex Converter
This converter allows you to convert decimal (base-10) numbers into hexadecimal (base-16), and vice versa.
How to Use This Converter
- Enter a decimal number to get the hexadecimal equivalent
- Or enter a hexadecimal number to convert it back to decimal
This tool handles both directions of the conversion process.
Understanding the Conversion
Decimal is our standard number system, using digits 0-9. Hexadecimal extends this by using digits 0-9 and letters A-F:
- Decimal 10 → Hex A
- Decimal 15 → Hex F
- Decimal 255 → Hex FF
Each hexadecimal digit represents 4 binary bits, which makes it very useful in computer systems and low-level programming.
Example
Convert 3735928559 (a classic number!) to hexadecimal:
373592855910 = DEADBEEF16
This is often used as a debugging marker in memory dumps.

Why Use Hexadecimal?
Hex is widely used in computing for representing memory addresses, color values in HTML/CSS, and compactly representing binary data.
For example, the RGB color #FF5733 is made of three hexadecimal values: FF (red), 57 (green), and 33 (blue).
