PsychroLib is a library of functions to enable the calculation of psychrometric properties of moist and dry air. Versions in Python, C, Fortran, JavaScript, and Microsoft Excel Visual Basic for Applications (VBA) are available. The library works in both metric (SI) and imperial (IP) systems of units. For a general overview and a list of currently available functions, please see the overview page.
