## Calculator of Air Description
This is a psychrometric (moist air) calculation app used in over 20 countries worldwide.
It allows you to quickly and easily calculate humidity-related properties with a calculator-like interface.
The app adopts the Wexler–Hyland formulation combined with numerical analysis, providing highly accurate and stable results even under extreme atmospheric conditions.

Supported parameters
The following six parameters are supported:

* Dry-bulb temperature
* Wet-bulb temperature
* Dew point temperature
* Relative humidity
* Humidity ratio
* Enthalpy

By entering any two of these parameters, all remaining values are calculated automatically.
For example, you can determine the dry-bulb temperature when the dew point and relative humidity are known.
Ideal for HVAC design, cleanroom management, and industrial drying processes where precision is non-negotiable.
When used together with the companion app “HumidCalc”, additional air-property parameters can be viewed
(please refer to the companion app description for details).

■ Input range and safety checks
* Temperature: -273.15 °C to 99.97 °C (-459.67 °F to 211.95 °F)
* Relative Humidity: 0 %RH to 100 %RH
* Atmospheric pressure is fixed at the standard atmospheric pressure (1013.25 hPa / 29.92 inHg).
If physically invalid values are entered(e.g., wet-bulb temperature higher than dry-bulb temperature), an error message is displayed before calculation is executed.

■ Additional features
* Supports both Celsius (°C) and Fahrenheit (°F)
* Toggleable click sound
* Available in Japanese, English, and Traditional Chinese

■ Memory function
After performing a calculation, tapping one of the following buttons(Dry-bulb, Wet-bulb, Dew point, Relative humidity, Absolute humidity, or Enthalpy) stores that value for subsequent calculations.
By using this function, continuous air-state calculations are possible.
For example, when outdoor temperature and humidity and indoor temperature are known(assuming no latent heat load), you can first calculate and store the outdoor dew point, then input the indoor temperature to easily obtain the indoor humidity.

■ Disclaimer
1. Recommended operating temperature range is approximately 0 °C to 40 °C.
Extremely unusual conditions may result in inaccurate calculations.
2. Minor numerical errors may occur due to floating-point arithmetic.
3. The developer assumes no responsibility for any damages resulting from the use of this app.

## Calculator of Air Reviews in Vereinigte Staaten

### ***** "Good app"
I’ve been using this for a while, it works !
-- Nicknamiouse incognito, 2023-05-19

### ****- "Good but too many digits"
There are way too many digits in the output values. I’d suggest 3 significant figures or make it a user option. A very useful app otherwise!

### *---- "Enthalpy?"
Just to cross ck proper use:

1) Don’t I need return & supply WB to ascertain change in ethalpy?  There is only 1 temp & 1 WB entry - so how are we calc enthalpy

2) For TTL btu change I’d need the enthalpy X ACFM.  Where is the function to make this final reading?
-- Squating Dog AKA The Kid, 2019-11-29

### ***** "very good"
I need to calculate the RH% inside a house given the outside temp, outside RH%, and indoor temperature. This requires two steps. First calculate dew point of outside, then using same dew point and indoor temp, calculate indoor RH%. But this calculator erases the dew point when I’m at step 2 entering the indoor temp. I have to memorize the dew point and re-enter it. Another minor thing is it displays too many digits.
P.S. The developer taught me a trick. At step 2 before entering the temp, press the dew point button first, then the dew point number will stay. I added one more star to the review.

### ***** "Great App"
If you need to know relative humidity get this app.  Faster and easier to use than humidity charts.
