Features Forex Position Size Calculator

An answer to the question below for Forex market ;I want to open position and am willing to risk at most some percent of my capital if things go wrong.
I (scientifically ?!) calculated my stop loss distance to be some pips away from my (buying/selling) price.
Given all of the above what is the maximum size I should open position with ?* Pip value for calculated size is displayed along with quote used to calculate position size.Note : If you know the exact amount to risk and want to do calculation using that amount (instead of % of total capital), then entering that amount as "trading capital" and entering 100 as "max percentage to risk" will do the trick.
Thanks to Phil Casey for pointer.
