Good app
I’ve been using this for a while, it works !Nicknamiouse incognito

Sorry for the very late reply. Thank you for your high evaluation! The "Calculator of Air" implements a memory function, and by utilizing this function, you can use this application even more conveniently. As an example, we will explain how to calculate the relative humidity when outdoor air is taken into a room and then heated. ＊When humidification is not performed. 1: Enter the temperature and humidity of the outside air into the "Calculator of Air". 2: Press the "Dew Point" button. 3: Next, press the "TEMP." button and after entering the indoor temperature, press "ENTER". With this simple operation, you can calculate the indoor humidity. If you have a chance, please try it.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!

I sincerely apologize for the delay in my reply to you. There is a way to alleviate the inconvenience caused by the large number of digits in this app. The app has a function where if you press "TEMP." or "Wet Bulb" or "Dew Point" or "HUMID." or "HUM Ratio" or "Enthalpy" after performing a calculation, the value of the button you press will be retained and all other values will be erased. With this function, for example, if you are calculating the outdoor dew point temperature from the outdoor temperature and outdoor humidity, and then the indoor humidity from the indoor temperature and the outdoor dew point temperature, then you can easily calculate the indoor humidity from the operations described below. (1)First of all, calculate the dew point temperature from the outdoor temperature and the outdoor humidity using this app. (2)In that state, please tap the "Dew Point" button. All numerical values other than "Dew Point" are erased from the calculation result screen, and only the numerical value of "Dew Point" remains. (3)In that state, enter the indoor temp and tap the "ENTER" button. This app calculates indoor humidity. I'm sorry, I'm Japanese so I'm bad at English.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

I read your review, but there are some incomprehensible points in your review, and your review has words that I don't understand. The following is a summary of those things, so please have a look. For question 1, you may have misunderstood this app. This app is an application to facilitate the calculation of humidity charts, but it's not an application for checking changes in enthalpy, so there's only 1 TEMP and 1 WB entry. By the way, the approximate formula for calculating enthalpy(btu/lb) is as follows. btu/lb = 0.24t + (0.44t + 1061.13)x t --- Fahrenheit temperature(℉) x --- Humidity ratio(lb/lb) For question 2, I am sorry, I don't understand the meaning of the following words. - TTL btu - X ACFM If you explain that to me, I may be able to give you good advice.
