Wat is dauwpunt?
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.
Magnus-formule
α = (A × T) / (B + T) + ln(RH / 100)
Td = (B × α) / (A − α)
Waarbij A = 17,27, B = 237,7 °C, T = temperatuur (°C), RH = relatieve vochtigheid (%), Td = dauwpunt (°C)

Dauwpuntcomfortniveaus
| Dauwpunt (°C) | Comfortniveau | Beschrijving |
|---|---|---|
| < 10 | Droog | Very comfortable, dry air. |
| 10 – 16 | Comfortabel | Pleasant conditions. |
| 16 – 18 | Enigszins vochtig | Most people comfortable. |
| 18 – 21 | Vochtig | Some discomfort, sticky feeling. |
| 21 – 24 | Zeer vochtig | Uncomfortable, oppressive. |
| > 24 | Extreem vochtig | Dangerous, heat exhaustion risk. |
Belangrijke opmerkingen
- Dew point is always ≤ air temperature.
- De Magnus-formule is nauwkeurig voor −45 °C tot 60 °C.
- Relative humidity must be between 0 % and 100 %.
- Dew point is a better comfort indicator than RH alone.
