Wind Chill Calculator
| |
Wind Chill is the temperature that it "feels like" based on actual temperature and wind speed. The "new" wind chill reflects the 2000-2001 National Weather Service update to the original ("old") 1945 index. For more information about wind chill go here... |

Heat Index Calculator
| |
Heat Index is the temperature that it "feels like" based on actual temperature and humidity. Note: air temperature must be greater than 80 °F ( 27 °C ) and relative humidity must be higher than 40 percent. |
|
Relative Humidity Calculator
| |
Humidity is the ratio of the actual moisture content of the air at a specific temperature to the maximum amount that the air could hold at that temperature. |

Pressure
Calculator
| |
Barometers measure air pressure in "millibars" (mb), "inches of mercury" (in) or "millimeters of mercury" (mm). Average sea level pressure is 1013.25 millibars (29.92 inches of mercury, 760 millimeters of mercury).
