Instructions
PsyCalc® is used to find psychrometric properties of an air sample when two properties are known.
Use the button at the top to toggle between IP (inch-pound commonly called English)
or SI (System International commonly called metric) units.
Configure each input's property using its dropdown then enter it's value.
PsyCalc® returns a set of psychrometric properties for the point.
The third input set is for elevation above sea level
or an absolute pressure.
Use Save as Defaults to save the current property values as your start up values. These will be saved in a cookie for 1 year.
