That would depend on how long the stem is.
This is a threadless stem? Figure out how much you want to raise the handlebar then take the stem to a shop and eyeball it side by side with the other stems to get the result you want.

Well, going back to basic Geometry without knowing
the length of the stem its really impossible to figure out.
you don't have both angles needed to calculate, nor the
side (length)
Must have stumped you too if you're asking here :D

This is the formula to get the amount of change in height:

cx[(v x t)+y-e]/3.14^ where v = ?

I've always found this chart (http://www.habcycles.com/fitting.html) helpful.

Of course it stumped me.Thats why i asked.I have a 100mm,6degree stem.I want a little less then a inch rise but that will bring the bar closer to so i need it to be longer to keep the bars the same distance from me as they are now.

6 degree stem? I'v heard of 73 degree, 90 degree, 120 degree, but never 6 degree.
