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 ). 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 ). Celsius to Fahrenheit formula F C 1.8000 + 32.00 Why is converting Celsius to Fahrenheit so difficult Because both Celsius and Fahrenheit scales are offset ie neither are defined as starting at zero. This is the definition that was used up until 2019, when the kelvin was redefined based on the definitions of the second, meter, and kilogram. 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. In 1954, the unit, 'degree Celsius,' as well as the Celsius scale were again re-defined to instead be based on absolute zero (-273.15 C) and the triple point of VSMOW (specially purified water). Now Outlook displays temperatures in Celsius. To display temperatures using the Celsius scale, follow these steps. By default, Outlook displays temperatures using the Fahrenheit scale. Temperature Conversion Enter a number then click on the appropriate number to see the result. Change the temperature from Fahrenheit to Celsius.

If a value you are interested in is not displayed, use the calculator above to convert the temperature, or view the conversion tables page which features temperatures between -460 and 379 Fahrenheit (☏), converted to Celsius (☌).Great thanks to Ron Murphy of WFO Binghamton NY for writing all of the code used on this page!įor more information about the indices and equations used Fahrenheit To Celsius Conversions Fahrenheit (☏) This table shows a select range of temperatures, converted from Fahrenheit to Celsius (F to C) - from absolute zero to the boiling point of water. Therefore, 70 Fahrenheit (☏) is equal to 21.11 Celsius (☌)Ĭheck this result with the conversion calculatorĪlbert Einstein is shown for illustrative purposes.Īnders Celsius (1701–1744), is the proponent of the Celsius temperature scale.
