FizzyCalc

FizzyCalc is a Windows application that allows simple conversion of coordinates to various formats. It takes coordinate strings in a variety of formats and generates copy-and-paste versions of those coordinates in a variety of other formats. FizzyCalc also does high-accuracy distance calculations and projections using the Vincenty method for calculating distances on an ellipsoid. These calculations are much better than you can obtain from your GPS unit or most other software out there.
