Decimal to Hexadecimal Conversion Calculator
Use this tool to convert decimal numbers into hexadecimal format. Perfect for developers, students, and electronics engineers working with base-16 systems.
Understanding Decimal to Hexadecimal Conversion
What is Decimal?
The decimal system, also known as base-10, is the standard system for denoting integer and non-integer numbers. It is the most widely used number system in everyday life and is based on ten symbols: 0 through 9.
What is Hexadecimal?
Hexadecimal, or base-16, is a positional number system that uses 16 distinct symbols: 0–9 to represent values zero to nine and A–F to represent values ten to fifteen. It is commonly used in computing and digital systems because of its direct relationship with binary and ease of readability.
Why Convert Decimal to Hexadecimal?
Decimal to hexadecimal conversion is essential in computer science, electronics, and programming. Hexadecimal numbers are compact, readable, and can easily represent long binary sequences, which makes them ideal for memory addressing, color codes in web design, and debugging machine-level code.
How Decimal to Hexadecimal Conversion Works
The process involves dividing the decimal number by 16 and recording the remainder. The remainder is then translated to its hexadecimal equivalent. The division continues until the quotient is 0. Finally, the hexadecimal number is read from bottom to top (last remainder to first).
Here is a step-by-step example for converting 254:
- 254 ÷ 16 = 15 remainder 14 → E
- 15 ÷ 16 = 0 remainder 15 → F
So, the hexadecimal representation of 254 is FE.
Practical Examples
| Decimal Number | Hexadecimal Equivalent |
|---|---|
| 10 | A |
| 15 | F |
| 255 | FF |
| 4095 | FFF |
Frequently Asked Questions
Can the calculator handle large decimal numbers?
Yes, the calculator can convert very large decimal numbers into their hexadecimal equivalents, limited only by your device’s processing capability and browser memory.
What are some practical uses of hexadecimal numbers?
Hexadecimal numbers are commonly used in:
- Memory addresses in computer architecture
- Web color codes (e.g., #FF5733)
- Assembly language and machine-level debugging
- Embedded systems and firmware development
How do I convert a negative decimal number?
This calculator handles only non-negative decimal numbers. For signed conversions (e.g., two’s complement), specialized converters are required.
Is hexadecimal case-sensitive?
No. Hexadecimal digits A–F can be represented in uppercase or lowercase without affecting the value. For example, 1F and 1f are equivalent.
