Hi Kevin,I do not understand the question. If you change your GPS Options to use units of Metric you will get the GPS accuracy in meters. If you switch to Imperial you will get the accuracy in feet. The "G" key will tell you the current accuracy of the system in either feet or meters depending upon what your system units are set to.
If your question is more of the mathematics behind the accuracy this is somewhat complicated but you can email me off line and I will be more than happy to enlighten you with the gory details (smile).
