How to calculate new attribute from geometry

I have generated a grid of points that have elevation values and want to calculate the UTM scale factor for each of these points. The data is currently in Lat/Long, but I think I can figure out how to do a spatial filter to extract the data in the specific UTM zone I am working in (Longitude between 79 and 84 west). The formulae requires the elevation and the UTM Easting (X) value. Once I filter my data, how do I convert it to a format that includes the coordinates as attributes so that I can do the calculation?
