How do you calculate dew point temperature

How do I calculate dew point?
where Td is dewpointtemperature (in degrees Celsius), T is observed temperature (in degrees Celsius), and RH is relative humidity (in percent). Apparently this relationship is fairly accurate for relative humidity values above 50%. More details can be found in the article

Dew Point Calculator
DewPointCalculator is a web resource created by the Image Permanence Institute to help express and visualize the relationship between temperature, relative humidity and dewpoint.

How Do You Calculate the Dew Point? -
To calculatedewpoint, you need to know the current temperature and relative humidity, and then solve the equation Td = T - ((100 - RH) / 5) for Td, which stands for the dewpointtemperature in degrees Celsius. This equation is accurate for humidity values above 50 percent.

How to Calculate Dew Point, Temperature and Relative Humidity
Education Temperature, relative humidity and dewpoint are all related to one another. Temperature is the measure of the energy in the air, relative humidity
