How This Is Calculated


$$ T_d = T - \frac{100 - \phi}{5} $$ where:

Td   =   Dew point temperature   (°C)

T   =   Air temperature   (°C)

φ   =   Relative humidity   (%)


Assumptions


  • Air behaves as ideal gases.
  • The formula is empirical.
  • Humidity level is moderate.
  • Atmospheric pressure remains constant.
