Select the ECEF (Earth Centered - Earth Fixed) or geodetic (LLA: Latitude, Longitude, Altitude) coordinate you want to convert using the form below.

NOTE: When converting from LLA, the type of altitude used must be specified. Typically GPS units report altitude in HAE (Height Above Ellipsoid) but often what is needed is a MSL (Mean Sea Level) altitude. AGL (Above Ground Level) conversions are available for registered users.
