Hi people,

I am creating an application where I need to show to the user a proximity radius. I know I can draw a circle with canvas.drawCircle(), but the input it requires is in pixels.
So my questions are as followed, how do I calculate the radius of a circle which needs to be for example 5 kilometers into pixels?
And how do I keep it in the correct perspective when zooming?

Man how could I have been so blind, after digging around I found the following method:



This should give me a radius in pixels of 2.4 kilometers. Unfortunately it's not 2.4 kilometers, more like 1.5... Strange, but it will have to do I guess...
