Compute relative humidity from dew point and temperature, or from wet-bulb readings.
由气温与露点,按 Magnus 关系反算相对湿度。
| Item | Formula / Note | Source / Standard |
|---|---|---|
| Relative humidity | RH = e/e_s(T) × 100% | WMO No.8 Vol.1 |
| Magnus formula | e_s = 6.112·exp(17.62T/(243.12+T)) | Magnus formula |
| Dew point inverse | Td from inverted Magnus | Bolton 1980 |
| Temperature coefficient | RH drops ~5% per 1 °C warming | Atmos. thermodynamics |
| Measurement | ≥2.5 m/s ventilation | WMO No.8 §5 |
| Comfort range | 30–60% comfortable | ASHRAE 55 |
