## Weather Calc Description
If you’re a pilot, you often need to make lots of weather related calculations. Now there’s an easy solution, as close as your iPhone. 

Weather Calc performs the following weather relation calculations: 
 
Altimeter Setting - compute the altimeter setting based on elevation and station pressure 
Cricket Temperature - just for fun! This lets you estimate the temperature based on the chirp rate of a cricket
Heat Index - compute the heat index based on the temperature and relative humidity 
Pressure - convert between hPa, atmospheres, psi, and inches and mm of mercury (Hg) 
Relative Humidity - compute the wet bulb and dewpoint based on the temperature, pressure, and relative humidity 
Speed Of Sound - displays the speed of sound in various units, given the temperature
Standard Atmosphere - compute the temperature, pressure, density, viscosity, speed of sound, and more 
Station Pressure - compute the station pressure based on the elevation and altimeter setting. 
Temperature - convert between degrees Fahrenheit, Celsius, Kelvin, and Rankine 
Virtual Temperature - compute the virtual temperature based on the temperature, dewpoint, and pressure 
Vapor Pressure - com[ute the saturated and actual vapor pressure, as well as relative humidity 
Wet Bulb - compute the dewpoint and relative humidity based on the temperature, pressure, and wet bulb reading 
Wind Chill - compute the wind chill based on the temperature and wind speed 
Wind Speed - convert between knots, kilometers/hour, meters/second, miles/hour, feet/second
