There is an Approximate-Transverse-Mercator algorithm suitable for shirt pocket calculators that converts latitude and longitude to rectangular coordinates. So it's Lat * 60 * 1852 for the North coordinate in meters and it's Lon * 60 * 1852 * Cos(Lat) for the East coordinate in meters. And that's it ? No...the Cos function is an extreme result at larger longitudes but a moderate result
