Valid entries are, air temperatures greater than 80 ☏ ( 27 ☌ ), dew point temperatures greater than 65 ☏ ( 12 ☌ ), and relative humidities higher than 40 percent.Įnter in the air temperature ( T air ) and the dew point temperature ( T dp ) in degrees Celsius, then click on the Calculate HI to compute the heat index ( HI).Įnter in the air temperature ( T air ) the dew point temperature ( T dp ) in degrees Fahrenheit, then click on the Calculate HI to compute the heat index ( HI).Įnter in the air temperature ( T air ) in degrees Celsius and relative humidity ( RH ) in percent ( without the % sign ), then click on the Calculate HI to compute the heat index ( HI ).Įnter in the air temperature ( T air ) in degrees Fahrenheit and relative humidity ( RH ) in percent ( without the % sign ), then click on the Calculate HI to compute the heat index ( HI ). Relative Humidity Calculation using degrees CelsiusĮnter in the air temperature ( T air ) and dew point temperature ( T dp) in degrees Celsius ( oF ) then click on the Calculate RH to compute the relative humidity ( RH ). Relative Humidity Calculation using degrees FahrenheitĮnter in the air temperature ( T air ) and dew point temperature ( T dp) in degrees Fahrenheit ( oF ) then click on the Calculate RH to compute the relative humidity ( RH ). Temperature Unit Conversion: Formulas: Heat Index: Formula: Wind Chill : Formulas: Cricket Chirps (Just for fun) Formula: Moisture Conversions : Dewpoint and Wet-bulb from Relative Humidity: Formulas: Relative Humidity and Wet-bulb from Dewpoint: Formulas: Relative Humidity and Dewpoint from Wet-bulb: Formulas: Vapor Pressure: Formulas: Mixing. The lower and higher heat index increases the human discomfort in. The ideal heat index ranges from 80 degrees Fahrenheit to 101 degrees Fahrenheit with relative humidity ranges from 40 to 100. The following tables calculate Dew Point and Relative Humidity based on the observed wet bulb and dry bulb temperatures and the elevation at the site of the observation. Real feel heat index (HI) calculator to find the apparent air temperature which combines relative humidity & air temperature. Wind Chill/Temperature Index Calculation in degrees CelsiusĮnter in the air temperature ( T air ) in degrees Celsius and wind speed in miles per hour, then click on the Calculate WC to compute the windchill ( WC ). Elevation 8,501-11,000 feet (above 7,900 feet in Alaska), 21 in. When relative humidity value is 100 percent, it means dew. The Relative Humidity and Mixing Ratio are calculated from the values input. The higher the relative humidity goes, the closer dew point gets to current temperature of the air. Wind Chill/Temperature Index Calculation in degrees FahrenheitĮnter in the air temperature ( T air ) in degrees Fahrenheit and wind speed in mile per hour ( mph ), then click on the Calculate WC to compute the windchill ( WC ).įor more information about windchill (ie. This calculator shows the inter-relationship of air temperature and moisture content with dew point and wet-bulb temperature as measured by a psychrometric thermometer. Temperature Conversion Enter a number then click on the appropriate number to see the result.
