Weather Calc vs WeatherLCD

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 Buy your copy now, and let Weather Calc take the drugery out of weather related calculations.

Why pay for multiple apps that provide U.S. current conditions, forecasts, and radar, plus marine weather, when you can get it all and much more with WeatherLCD! On land: - Current U.S. weather conditions - Wind Chill/Heat Index - Dewpoint - 3-hour pressure trend - Decoded METARs & TAF data (where available) - Forecasts (including hourly forecasts and snow accumulation forecasts) - In-depth technical discussions - Alerts (including high surf & rip current) - Animated radar (short-range and Regional GOES-16/17) - City/Zip Code search - Map-based Search - Network/GPS location - Metric conversion (except alerts, snow accumulation, and discussion) Alaska weather note: Some Alaska weather data is experimental and may not be available in all areas at all times. On the water: - Buoy observations - Detailed wind, wave, and other marine condition predictions for the U.S. Pacific Atlantic, and Gulf Coasts, plus Alaskan waters and U.S. portions of the Great Lakes, Puerto Rico/U.S. Virgin Islands, and Guam/N. Mariana Islands. - Area forecasts farther off shore - Hazardous marine condition bulletins/warnings - Swell height/period for Pacific locations - Text forecasts for Lake Champlain & Lake Tahoe - Metric conversion (except alerts) In the air: - Interactive global air turbulence map primarily based on pilot reports (PIREPS) - Color-coded pins make it easy to grasp turbulence severity - Touch any pin to get details such as reported turbulence altitude range, frequency, and type (chop, clear air turbulence, low-level wind shear, or mountain wave) if reported - Determines aircraft type or airline associated with report, and links to Wikipedia articles. (Note to non-US customers: the vast majority of turbulence reports displayed by WeatherLCD are from the US (incl. AK & air routes to HI) and Canada. A few times a day there are reports from the North Atlantic, Western Pacific, and Caribbean. It is very rare to see data points in other than the aforementioned locations.)
