Unlike the octal numbering system, hexadecimal numbering system is used a lot in mathematics and computing. It is a base sixteen (16) numbering system that consists of sixteen digits, that is, 0 to 9 and A to F. Similarly to decimal to octal conversion, you need to use binary in between whenever you are converting from decimal to hexadecimal.
