If you want to get the current atmospheric pressure, the current dry-bulb temperature(Td) and the current wet-bulb temperature(Tw), tap the "Weather" information button.

Furthermore, the app calculates the air condition from dry-bulb temperature(Td) and wet-bulb temperature(Tw) obtained by Assmann-Psychrometer, etc., and the app can also input atmospheric pressure.

For natural wet-bulb temperature(Tnw), convert the Wet-bulb temperature(Tw) obtained by measurement by the Assmann Psychrometer to the Wet-bulb temperature(Tw) measured in natural state, a use it as Natural wet-bulb temperature(Tnw).

Even if you enter the measurement value such as a non-draft type psychrometer(for example, "Augusto Psychrometer", etc.), just tap the button and the corresponding value can be displayed (※ the app is subject to use of a ventilation type psychrometer in terms of measurement accuracy).

The app can calculate 11 items and 13 indicators, and conversion to the Celsius temperature and SI units (or in the Fahrenheit temperature and Imperial and US customary measurement systems) also you can simply by switching of "Temperature Unit".

The calculation formula of the outdoor WBGT is "WBGT = 0.7 Tnw + 0.1 Td + 0.2 Tg", but since there is no entry a item Globe thermometer temperature(Tg) in the app, so estimation the Globe thermometer temperature(Tg) by Dry-bulb temperature(Td).

You can choose conditions of the wet bulb is you can choose any one of the “Normal" or “Froze” (※ If you choose the “Froze”, setting is enabled in when if sub-zero in wet-bulb temperature(Tw) ).

Input range is the temperature is -30 ℃ to 50 ℃ (-22 ° F to 122 ° F), the atmospheric pressure is 600 hPa to 2475 hPa(17.72 inHg to 73.09 inHg).

If you use this app, you can easily obtain "Temperature-humidity index(Discomfort Index)", "WBGT(Heat stroke index)", "Dew point temperature", etc., from weather information.

The app can receive the calculated value of dry bulb temperature (Td) and wet bulb temperature (Tw) from the sister app “Calculator of Air”.

Please input and use the temperature range(0 ℃ to 40 ℃ / 32°F to 104°F ) according to common sense as much as possible.

There is a very strong correlation between Globe thermometer temperature(Tg) and Dry-bulb temperature(Td).

The natural state here means that the wind speed at the time of measurement is 5 meters per second(16.4 feet per second) or less.

If you use this function, you can input "dew point temperature", "relative humidity", etc.
