Methods to translate geoidal heights from a certain coordinate system to an arbitrary system with the corresponding ellipsoid are studied. We propose a simple method, which ignores the errors due to the difference in normals of two ellipsoids, for general users of grid data of geoidal heights. The simple method is easy to understand, and reducesmistakes and loads to computers in calculation. Moreover the errors are very small compared to those of grid geoidal heights. I adopted this method and developed a software "jgeoidtrn 97 for Windows 95", which enables users to calculate geoidal heights in their coordinate systems with ellipsoids, such as ITRF 94 with GRS-80, WGS-84 with WGS-84, and Tokyo 97 coordinate system with Bessel ellipsoid.
