Co to jest punkt rosy?
The dew point is the temperature at which air becomes saturated with water vapor and condensation starts to form. It is always less than or equal to the air temperature. Dew point is a better indicator of comfort than relative humidity alone, because it directly measures the amount of moisture in the air. This calculator uses the Magnus formula, widely used in meteorology and HVAC applications.
Formuła Magnusa
α = (A × T) / (B + T) + ln(RH / 100)
Td = (B × α) / (A − α)
Gdzie A = 17,27, B = 237,7 °C, T = temperatura (°C), RH = wilgotność względna (%), Td = punkt rosy (°C)

Poziomy komfortu punktu rosy
| Punkt rosy (°C) | Poziom komfortu | Opis |
|---|---|---|
| < 10 | Suchy | Very comfortable, dry air. |
| 10 – 16 | Wygodny | Pleasant conditions. |
| 16 – 18 | Lekko wilgotny | Most people comfortable. |
| 18 – 21 | Wilgotny | Some discomfort, sticky feeling. |
| 21 – 24 | Bardzo wilgotno | Uncomfortable, oppressive. |
| > 24 | Niezwykle wilgotny | Dangerous, heat exhaustion risk. |
Ważne uwagi
- Dew point is always ≤ air temperature.
- Wzór Magnusa jest dokładny dla temperatur od -45°C do 60°C.
- Relative humidity must be between 0 % and 100 %.
- Dew point is a better comfort indicator than RH alone.
