EMU: English Metric Unit, EMUs are used for coordinates in vector-based drawings and embedded pictures. One inch equates to 914400 EMUs and a centimeter is 360000. For bitmaps the default resolution is 96 dpi (known as PixelsPerInch in Excel). Spec p. 1122

For radial geometry Excel uses integert units of 1/60000th of a degree.
