What Is Mixed Air?
Mixed Air calculates dew point, heat index, and air density from temperature, humidity, and altitude.
Formula
Dew point approximation, heat index (simplified), air density with altitude correctionFrequently Asked Questions
How does altitude affect air density?
Air density decreases exponentially with altitude. At 10,000 ft it's roughly 75% of sea level.
