How do you convert decimal to hexadecimal?

Divide the decimal number by 16 repeatedly, keeping track of the remainders. Convert remainders 10-15 to letters A-F. Read remainders from bottom to top. For example, 255: 255÷16=15 remainder 15 (F), 15÷16=0 remainder 15 (F). Result: FF.

What is decimal 255 in hexadecimal?

Decimal 255 in hexadecimal is FF. This is because 255 = (15×16¹) + (15×16⁰) = 240 + 15, and 15 in hex is F.

Why use hexadecimal instead of decimal?

Hexadecimal is more compact than binary (one hex digit = 4 bits) and easier to read than long binary strings. It's the standard way to represent binary data in programming, debugging, and digital systems. Memory addresses, color codes, and file formats commonly use hexadecimal.

What do the letters A-F represent in hexadecimal?

In hexadecimal, A=10, B=11, C=12, D=13, E=14, F=15. These letters represent decimal values that exceed 9, allowing hexadecimal to use base 16 with single-character digits.

How is hexadecimal used in web development?

Hexadecimal is extensively used for color codes in CSS and HTML. Colors are represented as #RRGGBB, where each pair is a hex value from 00 to FF. For example, #FF0000 is red, #00FF00 is green, and #0000FF is blue.

Can I convert decimal fractions to hexadecimal?

Yes, but it's more complex. Multiply the fractional part by 16 repeatedly, taking the integer part each time. The process may continue indefinitely for some fractions, similar to decimal fractions.
