Receive Text 63. so it is now in 63hex. No, it isn't, is it? It is just two characters - a '6' and a '3' - they could equally well represent a decimal number, or an octal number, etc... but need to convert it hex code. 63 to 3f. Do you understand how position value works? In decimal, you have units, tens, hundreds, thousands, etc; or, mathematically, 100, 101, 102, 103, etc In hexadecimal, it's 160, 161, 162, 163, etc So you have to multiply the value of each digit by its position value - and the value of the overall number is the sum of its digit values.
