  "content": "<p>Hexadecimal to octal conversion is the process of converting a hexadecimal (base-16) number into its octal (base-8) representation.</p><p>In the hexadecimal system, numbers are represented using the digits 0 through 9 and the letters A to F.</p><h2>Steps to Convert Hexadecimal to Octal</h2><p>Here are the steps to convert a hexadecimal number to octal:</p><ol class=\"steps\"><li>Convert each hexadecimal digit to its equivalent 4-bit binary representation.</li><li>Group the binary digits into sets of three, starting from the right.</li><li>Convert each group of three binary digits to its equivalent octal representation.</li><li>If necessary, add leading zeros to make each group have three digits.</li><li>Concatenate the octal representations to get the final result.</li></ol><h2>Example</h2><p>Let's take an example to illustrate the process. Suppose we want to convert the hexadecimal number <strong>1A3</strong> to octal:</p><ol class=\"steps\"><li>Convert each hexadecimal digit to its 4-bit binary representation: <strong>0001 1010 0011</strong>.</li><li>Group the binary digits into sets of three: <strong>000 110 100 011</strong>.</li><li>Convert each group to octal: <strong>0 6 4 3</strong>. You may leave out the leading zeroes making the answer <strong>643</strong>.</li></ol><p>Therefore, <strong>1A3</strong> in hexadecimal is equal to <strong>643</strong> in octal.</p>"
