Vad är Dew Point?
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 Formula
α = (A × T) / (B + T) + ln(RH / 100)
Td = (B × α) / (A − α)
Där A = 17,27, B = 237,7 °C, T = temperatur (°C), RH = relativ fuktighet (%), Td = daggpunkt (°C)

Komfortnivåer för daggpunkt
| Daggpunkt (°C) | Komfortnivå | Beskrivning |
|---|---|---|
| < 10 | Torka | Very comfortable, dry air. |
| 10 – 16 | Bekväm | Pleasant conditions. |
| 16 – 18 | Något fuktigt | Most people comfortable. |
| 18 – 21 | Fuktig | Some discomfort, sticky feeling. |
| 21 – 24 | Mycket fuktigt | Uncomfortable, oppressive. |
| > 24 | Extremt fuktigt | Dangerous, heat exhaustion risk. |
Viktiga anmärkningar
- Dew point is always ≤ air temperature.
- Magnus formel är korrekt för −45 °C till 60 °C.
- Relative humidity must be between 0 % and 100 %.
- Dew point is a better comfort indicator than RH alone.
