Quick Answer

Absolute Humidity Converter: temp + RH → g/m³ via Magnus. Absolute Humidity Converter uses standard unit conversion formulas to compute accurate results instantly.

Absolute humidity13.79 g/m³
Saturation vapor pressure31.62 hPa
Actual vapor pressure18.97 hPa

How it works

  1. 1Magnus: es = 6.112 × e^(17.62t / (t+243.04)) = 31.62 hPa
  2. 2Actual = 60% × 31.62 = 18.97 hPa
  3. 3AH = 216.7 × e ÷ (273.15+t) = 216.7 × 18.97 ÷ 298.15 = 13.79 g/m³
RH swings hard with temperature: heat a winter room and the same water vapor drops RH from 60% to 20-30% - dry throat and static. Absolute humidity (g/m³) is the intuitive metric for dehumidifier/humidifier sizing; the comfort band is roughly 8-14 g/m³ (40-60% RH at 25°C). Rated dehumidification (L/day) and humidification need ≈ room volume × air changes per hour × humidity gap.
