From Everyday Numbers to Programmer's Code

Our Decimal to Hex Converter is an essential tool for bridging the gap between the decimal (base-10) number system we use daily and the hexadecimal (base-16) system that is fundamental to computer programming and web development. While we think in terms of tens, computers operate on a binary system, which is conveniently represented in a more compact form by hexadecimal numbers.

This conversion is crucial in many technical fields. Web designers use hex codes to define colors (e.g., decimal 255 becomes FF in hex), while programmers use them to work with memory addresses, bitmasks, and data representation. This tool removes the need for manual calculations, which involve repeated division and tracking remainders, giving you an accurate and instant conversion. It's the perfect utility for students learning number systems and professionals who need to convert values on the fly.

How to Use the Decimal to Hex Converter

1. Enter Decimal Number: Type the base-10 number you want to convert into the input field.
2. Select Formatting Options: Choose whether to add the standard 0x prefix or use uppercase (A-F) or lowercase (a-f) letters for your result.
3. Convert: Click the "Convert to Hex" button to get the hexadecimal equivalent instantly.
4. Copy and Go: Use the "Copy Result" button to easily transfer the hex code to your clipboard.

Frequently Asked Questions About Decimal to Hex Conversion

How do I convert decimal to hexadecimal?

To convert a decimal to a hexadecimal, you repeatedly divide the decimal number by 16. The remainders of each division, read from bottom to top, form the hexadecimal number. For remainders 10 through 15, you use the letters A through F. Our tool automates this entire process for you.

How to convert 100.25 decimal to hexadecimal?

This is a two-part conversion. First, convert the integer part: 100 divided by 16 is 6 with a remainder of 4, so the integer part is 64. Then, convert the fractional part: 0.25 multiplied by 16 is 4.0. So, 100.25 in decimal is 64.4 in hexadecimal. Note that our tool primarily handles integer conversions.

How to convert 122 to hexadecimal?

To convert 122 to hex, divide 122 by 16, which gives 7 with a remainder of 10. The remainder 10 is represented by the letter 'A' in hexadecimal. Therefore, 122 in decimal is 7A in hex.

What is 55 decimal to hexadecimal?

To convert 55 to hex, divide 55 by 16, which is 3 with a remainder of 7. Reading the quotient and then the remainder gives you the hex value. So, 55 in decimal is 37 in hexadecimal.

How do you convert base 10 to base 16?

Converting from base-10 (decimal) to base-16 (hexadecimal) involves the division method. You divide the base-10 number by 16 and note the remainder. You continue dividing the quotient by 16 until the quotient is 0. The hexadecimal result is the sequence of remainders from last to first.
