NOAA/ National Weather Service National Centers for Environmental … Athropolis - HOME | MORE CALCULATORS: TEMPERATURE CALCULATIONS Just enter a number in either field - then click outside the box. Wind increases the rate at which a body loses heat, so the air on a windy day feels cooler than the temperature indicated by a thermometer. PleaseRemainSeated.com accurate weather forecasting and conditions for the USA, Canada and most international cities. Winter Weather Forecasts … F °C = (°F - 32) / 1.8 K = °C + 273: C: WIND CHILL Wind increases the rate at which a body loses heat. Heat index is often referred to as humiture, and is similar to wind chill in its attempt to measure perceived, rather than actual temperature. The air on a windy … Wind Chill Calculator . Wind chill tables and calculators exist on the internet; refer to the Resources section for examples. This calculator uses the formula developed by the National Weather Service in the United States, which was listed below.

The following formula can be used to calculate a wind chill. Then Click Calculate. About the Calculator The Wind Chill Calculator calculates wind chill given a temperature in degrees Farenheit and a wind speed in miles per hour.

Wind Chill: A measure of the cooling effect of wind. As wind increases, heat is carried away from the body at a faster rate, driving down both the skin temperature (which can cause frostbite) and eventually the internal body temperature (which can kill). Then Click Calculate. To calculate wind chill, enter the current ambient temperature in degrees Fahrenheit (°F) and enter the speed of the wind in miles per hour; if you don't know those values in °F or MPH (statute miles per hour), enter them in °C and knots (often called nautical miles per hour), or KmPH (kilometers per hour) in the appropriate fields. You can find more on this topic below the tool. Temperature °F °C Wind Speed Mph Knots Wind Chill °F °C: Wind Chill Chart and Explanation. This relative humidity calculator can estimate the relative humidity, air temperature or dew point temp by taking account of the rest of the two variables from the formula.

The wind chill calculator only works for temperatures at or below 50 ° F and wind speeds above 3 mph. Temperature °F °C Wind Speed Mph Knots Wind Chill °F °C: Wind Chill Chart and Explanation. Windchill Calculator Windchill Temperature = 0.045*(5.2735*SQROOT(W) + 10.45 - 0.2778*W)*(T - 33.0)+33 WCF = 1.1626*(5.2735*SQROOT(W) + 10.45 - 0.2778*W)*(33.0 - T) where: ET = equivalent temperature (degrees Celsius) WCF = wind chill factor (Watts per square metre) SQROOT = square root function W = wind speed (Km/hr) T = air temperature (degrees Celsius)

Relative Humidity Calculation using degrees Celsius Enter in the air temperature ( T air) and dew point temperature ( T dp) in degrees Celsius ( o F ) then click on the Calculate RH to compute the relative humidity ( RH ).

Enter a temperature, in either Fahrenheit or Celsius. Conversion calculator, comparison table, definitions and links. Note that charts will outline how many minutes before frostbite can occur. For example, at 0 degrees Fahrenheit with a wind chill factor of 30 miles per hour, the frostbite time is 30 minutes.
