What is the equivalent?

What is the equivalent of a 6'4 MTN?
If you don't understand my question, look at it as an exchange: Height matters to an extent; let me give an example:
5'8 HTN=6'1MTN (This is an example, whether its right or wrong) Basically what im saying is SMV equivalent
So I just want to get an opinion

Equivalents are silly, it's not linear nor can be calculated
