This program will convert fundamental humidity quantities such as mixing ratio and specific humidity (see below for the complete list)

Features

• Input variables
  Mixing ratio (kg/kg)
  Dry bulb temperature (°C)
  Total atmospheric pressure (Pa)
• Constants (Which can be changed)
  Molar mass of vapour (kg/kmol)
  Molar mass of dry gas (kg/kmol)
  Universal gas constant (J/(kmol·K))
• Converts between
  Mixing ratio (kg/kg)
  PPMw
  Vapour mole ratio (mol/mol)
  Specific humidity (kg/kg)
  Vapour mole fraction (mol/mol)
  PPMv
  True vapour pressure (Pa)
  Volumetric humidity (kg/m³)
