I think > you should at least give inches of mercury as an option since that is what is > used in the US. It's a function of the way the data is decoded. For the ADDE data, the value is converted to millibars when decoded, so that's how it gets stored/displayed. Since you can't physically convert units of millibars to inches of mercury we don't list that as an option. There is an empirical conversion, but you cannot do unit math to make the physical conversion. When we get the GEMPAK surface data reading done, you can use ALTI as a parameter and display it in inches (but not in millibars).
