Weather Calc

iPhone Software to Perform Weather and Meteorology Calculations

Weather Calc performs the following weather relation calculations:

• Altimeter Setting - compute the altimeter setting based on elevation and station pressure
• 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
• 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
