This powerful geodesy application allows you to convert coordinates between many of the world's coordinate systems, calculate geoid offsets, and estimate current or historical magnetic field for any location. It also includes a calculator tool as well as surveying tools to calculate point scale factor, grid convergence, traverse, inverse, and solar angle. You can also store multiple points and calculate the length and area of the boundaries on them, or import / export them to CSV files. The application uses the PROJ4 library and a lookup file containing datum and projection parameters to support more than 1700 coordinate systems. Lat / lon, UTM, US Coordinate Systems (Including US State Plane), Australian Coordinate Systems (including GDA2020), UK Coordinate Systems (including Ordinance Survey) and many, many others are supported.
