Very Strange Temperature Conversion

Revit

I ran my own tests and came up with the same answer as @lucamanzoni
Accessing the values straight through the API yields correct values, however…

val_convert_c = UnitUtils.ConvertFromInternalUnits(val_internal, dut_c)

OUT = [[dut_f, val_convert_f],
	   [dut_c, val_convert_c],
	   [dut_k, val_convert_k],
	   [dut_r, val_convert_r],
	   ['INTERNAL', val_internal]]

This is showing that the value is stored internally in Kelvin, which aligns with what is stated on Autodesk’s website. None of the values for valid display unit types (fahrenheit, celsius, kelvin, rankine) are anywhere near the ~1.3 value.
