  "content": "<p>Decimal to hexadecimal (hex) conversion is the process of converting a decimal (base-10) number into its hexadecimal (base-16) representation.</p><p>In the decimal system, numbers are expressed using the digits 0 through 9, and in the hexadecimal system, numbers are represented using the digits 0 through 9 and the letters A to F, where A stands for 10, B for 11, C for 12, D for 13, E for 14, and F for 15.</p><h2>Stesp to convert decimal to hexadecimal</h2><p>Here are the steps to convert a decimal number to hexadecimal:</p><ol class=\"steps\"><li>Divide the decimal number by 16.</li><li>Record the remainder (which can be any digit from 0 to 15).</li><li>Divide the quotient obtained in step 1 by 16.</li><li>Record the remainder again.</li><li>Repeat steps 3 and 4 until the quotient becomes 0.</li><li>The hexadecimal equivalent is the sequence of remainders read in reverse order.</li></ol><h2>Example</h2><p>Let's take an example to illustrate the process. Suppose we want to convert the decimal number <strong>255</strong> to hexadecimal:</p><ol class=\"steps\"><li>285 ÷ 16 = 17 (E in hexadecimal) with a remainder of 13 (D in hexadecimal).</li><li>17 ÷ 16 = 1 with a remainder of 1.</li><li>1 ÷ 16 = 0 with a remainder of 1.</li></ol><p>Reading the remainders in reverse order gives us the hexadecimal equivalent: 11D.</p><p>Therefore, <strong>285</strong> in decimal is equal to <strong>11D</strong> in hexadecimal.</p>"
