Formel
Td = 243.04 × (ln(RH/100) + 17.625×T/(243.04+T)) / (17.625 − ln(RH/100) − 17.625×T/(243.04+T))
Häufig gestellte Fragen
What is the dew point?
The dew point is the temperature at which air becomes saturated and condensation begins to form.
What does condensation risk mean?
High risk means dew point equals or exceeds air temperature; moderate means within 3°C; low means well below air temperature.
