Question 1

How do you convert hex to decimal?

Accepted Answer

Each hex digit represents a power of 16, starting from the right at 16^0. Multiply each digit by its corresponding power of 16 and sum the results. For example, hex 1A = 1x16 + 10x1 = 26 in decimal. Letters A-F represent values 10-15.

A hex color code is a 6-digit hexadecimal number preceded by # that represents a color. The first two digits are the red value (00-FF), the middle two are green, and the last two are blue. For example, #FF0000 is pure red and #2563EB is blue.

Question 3

How do I convert RGB to hex?

Accepted Answer

Convert each RGB component (0-255) to a two-digit hex number and concatenate them with a # prefix. For example, RGB(37, 99, 235) converts to #2563EB where 37=25, 99=63, 235=EB in hexadecimal.

Question 4

What is the difference between hex and decimal?

Accepted Answer

Decimal (base-10) uses digits 0-9, while hexadecimal (base-16) uses digits 0-9 and letters A-F. Hex is commonly used in computing because each hex digit maps to exactly 4 binary bits, making it a compact notation for binary data.
