Psychrometric Dew Point Calculator

Calculate dew point temperature from dry bulb temperature and relative humidity. Magnus formula: T_d = 243.04·[γ/(17.625-γ)] where γ = ln(RH/100) + 17.625T/(243.04+T). Psychrometric chart properties.

2D stress state at a point. All stresses in MPa.

σx — Normal Stress X (MPa)
σy — Normal Stress Y (MPa)
τxy — Shear Stress (MPa)
⚙ Mechanical Note: Results are based on standard textbook formulas and ISO/AASHTO references. Always verify critical designs with applicable codes (ISO 898, AASHTO 1993, AISC, Eurocode 3) and a qualified engineer.

How It Works

Calculate dew point temperature from dry bulb temperature and relative humidity. Magnus formula: T_d = 243.04·[γ/(17.625-γ)] where γ = ln(RH/100) + 17.625T/(243.04+T). Psychrometric chart properties

Each component has a specific meaning:

  • Dry bulb temperature — The dry bulb temperature recorded for the patient or scenario being assessed.
  • Relative humidity — The relative humidity recorded for the patient or scenario being assessed.

Note: Interpret the dew point result against the clinical thresholds and context described above.

How to Use

Enter the dry bulb temperature, relative humidity for the patient or scenario you are assessing. Calculate dew point temperature from dry bulb temperature and relative humidity. Magnus formula: T_d = 243.04·[γ/(17.625-γ)] where γ = ln(RH/100) + 17.625T/(243.04+T). Psychrometric chart properties. Use the dew point result to inform your clinical assessment.
