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. These can be calculated automatically using Wildland Fire RH Calculator Apps for iOS and Android available for free.
The dew point chart tells you what a dew point temperature is at a certain temperature and at certain relative humidity. This chart is also referred to as the ‘dew point temperature chart’ or the ‘dew point humidity chart’ since it includes both T and RH.
This free dew point calculator calculates dew point, relative humidity, or air temperature if given any of the other two values.
To determine the Dew Point from the charts below, find the temperature of the air in question on the left side of the table. Next, locate the relative humidity of the air in question across the top of the table.
Dew point = Temperature at which condensation occurs Condensation is created as a function of relative humidity and air temperature. Example: For an air temperature of +20 ° C and relative humidity of 55%, the dew point will be created at +10.7 ° C. If the wall surface temperature is lower than 13.7 ° C (10.7 ° C + 3 ° C safety factor) we
The chart includes various dew point temperatures and the corresponding humidity levels and comfort levels. It’s color-coded for quick visual reference. Low dew points are in blue and indicate dry air, while high dew points are in red to show humid, muggy conditions.
This dew point calculator can be used to explore the relationship between dew point, temperature, and relative humidity, without the need for a dew point chart. If you have ever wondered "what is dew point?" or how to calculate relative humidity in certain conditions, then this calculator is for you!
Dew point temperatures from dry and wet bulb temperatures are indicated in the charts below. Moist and humid air calculations. Psychrometric charts and Mollier diagrams. Air-condition systems temperatures, absolute and relative humidities and moisture content in air.
Enter a temperature and a dew point, in either Fahrenheit or Celsius. Then click Calculate.
Dew point is the temperature at which moisture will condense on a surface. No coatings should be applied unless the surface temperature is a minimum of 5°F above this point. If the air temperature is 70°F and the relative humidity is 65%. The dew point is 57°F. The coatings should not be applied unless the surface temperature is a minimum of 62°F.
