Suppose we want to convert the octal number 345 to hexadecimal:</p><ol class=\"steps\"><li>Convert the octal number 345 to its binary equivalent. Result: 011 100 101.</li><li>Group the binary digits into sets of four from the right. You may add leading zeroes if required to the leftmost group. Result: 0000 1110 0101.</li><li>Convert each group to hexadecimal. Result: 0 E 5.</li><li>The hexadecimal equivalent is E5.</li></ol><p>Therefore, <strong>345</strong> in octal is equal to <strong>E5</strong> in hexadecimal.</p>"
