I've been searching through the neck tutorials on this site, and countless of hits on Google to figure out the equation to get the exact length of each fret to no avail.

if anyone knows what it is, it would be much appreciated if they could fill me in
thanks for the calculator, but i would like to know how exactly it calculates it.
seems like it just gets it from a big table they have stored after looking at the websites code
then that doesn't help me get the answer to my question D:

does any one actually know how?
