Hello Everyone, I am trying to make a reporting measure to display things like EUI and Energy use in Kill-watt Hour(Kwh) but the openstudio unit conversion is limited to GJ and J. How do I convert the unit to Kwh?

OpenStudio unit converter does do GJ to kWh:

#=> 277.77777777777777

Or you can hardcode it since you aren't changing unit systems. A watt is a joule per second, so a kilowatt-hour is (1000 joules / second) * (3600 seconds / hour) = 3.6*10^6 joules = 0.0036 gigajoules. (1/0.0036) = 277.77. So just divide GJ by 0.0036 to get kWh.
