Dew Point Humidity Calculator vs Allday HVAC Calc Usage & Stats
Dew Point Humidity Calculator App is the best app to find the temperature at which the water vapour of the atmospheric air must condense into liquid water and reaches its coolest point called the saturation. You can calculate the dew point temperature at which the air moisture converts into water using this calculator app.
There are two calculators that you can use:
1. Calculate Dew Point from Air Temperature and Relative Humidity (%)
2. Calculate Relative Humidity (RH) or Dew Point from Dry Bulb temperature, plus either Wet Bulb or Dew Point (Psychrometric Calculator)
The input units of temperature is Celsius (°C), Fahrenheit (°F) or Kelvin (K). We provide a unit converter to convert among these units.
You don't need to buy a physical Dew Point Calculator any more. Use this FREE app for your measurements.

The application can be useful for HVAC engineers and contains 3 modules.
Pipe Calculator - this module is used to calculate velocity and pressure loss in pipelines and to select pipeline diameters for a given maximum velocity and pressure loss. It can also be used as a reference for heat transfer fluid properties and pipe characteristics.Psychrometric calculator - allows for psychrometric calculations.
Duct Calculator - the module is used to calculate the speed and pressure loss in round, rectangular and oval air ducts when moving wet or dry air through them, as well as to select their sections for a given maximum speed and maximum pressure loss. Additionally, the heating or cooling power is calculated for a given air flow rate, or reverse calculations: air flow rate for a given power; temperature of incoming or outgoing air for a given power and flow rate. It can also be used as a reference material for determining the properties of wet and dry air at different pressures and temperatures.
Also in the description sections are the reference formulas by which the calculations are made.
