Thanks Linda….but when I factor W/m2 by .166667 to get Wh/m2 as input, calculation of direct normal still blows up….sometimes by a lot…

Sorry -- sent too soon.
There should be as many DataUnits entries as DataElement entries. These are not generally used but may be used in the future for automatic conversions. The exception to this is “temperature” fields. Use “f” for Fahrenheit, “k” for Kelvin temperatures. Note that the DataConversionFactor for this field will be applied prior to conversion. (Many formats use integer numbers to represent values that are in tenths, for example.)
There should be as many DataConversionFactors entries as DataElement entries. These factors are multiplicative factors (i.e. the input value is multiplied by this factor) and can be used to process input data into the values used in the
EPW weather files.
I am trying to use the weather converter to format my site weather station data. I find the help file lacking a concise list of conversion DataUnits.
