If you go down to bottom end of the page and to the right (under climate craft)below the download button, you will find description of 6 charts (3 in IP and 3 in SI units). Click each one of them and they open up into a pdf file of a psychrometric chart.
The units given are Enthalpy - kJ/Kg, Temperature - deg.C, Humidity Ratio - gms of moisture/Kg of dry air and Specific Volume - cu.m/kg. What units do you want?
I presume you downloaded the program instead.

Believe it or not : Had we trusted Archimedes and assigned him the work of lifting the earth(or any mass equivalent to that of earth on earth),with a lever of suitable length, it would have taken him 23 million million years to lift the earth by one centimeter, if he worked at the rate of 1 HP.
