Weather Station Calc & Toolkit

You take weather details seriously, and that deserves recognition. Thank you for using Weather Calcs. Whether you are checking local conditions, studying meteorology, planning outdoor work, or comparing weather units, the app gives you practical numbers without burying them in clutter. Weather Calcs combines nearby NOAA station observations, weather formulas, unit conversions, and readable reference material in one organized app for iPhone and iPad. CURRENT STATION WEATHER - Use your location to find the nearest station from the bundled NOAA station list. - See the station name, station ID, coordinates, and distance from your location. - Choose another station manually with fast station search. - Review temperature, humidity, wind, pressure, dewpoint, visibility, weather text, and observation time when those fields are reported. - See exactly when data was fetched and how old the saved observation is. - Keep the latest successful station observation available when you reopen the app. - View only the conversions supported by the values that the station actually supplied. WEATHER CALCULATORS - Heat Index - Wind Chill - Dewpoint and Wet-Bulb - Relative Humidity and Dewpoint - Relative Humidity and Wet-Bulb - Vapor Pressure - Mixing Ratio - Virtual Temperature - Station Pressure - Altimeter Setting - Pressure Altitude - Density Altitude - Wind Speed Conversion - Temperature Conversion - Pressure Conversion - Speed of Sound - Showalter Index - Distance Conversion - Centimeters and Meters Enter signed values, select the units that match your source, and get focused results in a compact table. Clear controls, visible input focus, and Next and Done keyboard actions make repeated calculations easier. Invalid input is identified instead of quietly becoming a misleading zero. SEARCH AND WEATHER REFERENCE - Search calculators by name, category, description, or input label. - Browse formulas by temperature, moisture, pressure, unit conversion, and advanced weather topics. - Read the equation or conversion constants used by each calculator. - Review what each input means and how the result can be used. - Learn about NOAA station identity, observation fields, station matching, and data limits. PRACTICAL HOME GUIDANCE WeatherCalcs can summarize clothing, precipitation, visibility, heat, cold, and wind considerations from available station fields. Guidance is withheld when the report time cannot be verified, the station does not match, or the data is too old. Tornado, thunder, lightning, and hail entries are labeled as historical station reports and direct you to verify current official warnings. SET IT UP YOUR WAY - Choose Fahrenheit or Celsius and preferred wind, pressure, and distance units. - Select System, Light, or Dark appearance. - Move quickly through Home, Calculators, Reference, Pro, Settings, Help, and About with adaptive navigation designed for iPhone and iPad. Weather Calcs is useful for weather enthusiasts, students, educators, outdoor planners, and anyone who wants to understand a station report. Live weather requires a network connection. Location is optional because stations can be selected manually. Station observations are not forecasts and may differ from conditions at your exact location. Weather Calcs does not replace official watches, warnings, forecasts, or professional operational guidance. Always verify safety-critical decisions with current official weather sources.
