excel macro binary to hex converter

I'm looking for an excel macro to convert a binary number (16 bits) to hexadecimal. Any help would be greatly appreciated.

 

Perhaps?

Thank you, this is what I was looking for...

 

I have modified the file mentioned in the post above and would like to share it at:

The file has one page for 16 bit binary numbers, which can be easily modified to have more bits. The other page is another way to convert 8 bit binary numbers to hex.
