This Psychrometric Calculator allows you to compute moist air properties given only altitude, dry-bulb temperature and either wet-bulb, dew point or relative humidity. Outputs include Atmospheric pressure, Humidity Ratio, Specific Enthalpy, Specific Volume and Partial Vapor Pressure. Imperial (IP) and Metric (SI) units are supported. Toggling between unit systems is in the option menu. You can also toggle lb/lb to Grains/lb and kg/kg to Grams/kg by clicking the button with the humidity ratio units.
