A free desktop version of the calculator is also available. You can download the weather calculator software here. Documentation and directions are available. You will need to unzip this file.
- Temperature Calculator
Convert Celsius, Fahrenheit, and Kelvin temperatures. You can also get the formulas for converting temperatures by going to the temperature conversion formulas page.
- Heat Index Calculator
Use relative humidity and temperature in either Fahrenheit or Celsius to determine how hot a temperature feels. Don't know what the Heat Index is? Check out this article on evaporative cooling.
- Air Pressure Calculator
Use several air pressure units including millibars, millimeters of mercury, hecto Pascals, standard atmospheres, inches of mercury, pounds per square inch, and more to convert air pressures. You can also check out the air pressure symbols used on weather maps or check out how to draw isobar pressure lines on a map.
- Wind Chill Calculator
As temperature decreases and wind speed increases, the body can feel much colder than the standard temperature reads. Use the wind speed and temperature to determine how cold the air outside feels in this easy calculator. Wind speed units include knots, miles per hour, meters per second, and kilometers per hour.
- Relative Humidity Calculator
Calculate using dew point and the wet bulb temperature. Other versions of the calculator are available if you need other conversions such as dew point or the wet bulb temperature.
- Cricket Temperature Calculator
Okay, so this one is more fun than anything...But there is some truth to the idea of calculating temperature based on crickets. This is one bit of weather folklore that proves true!
