Wet Bulb Temperature Calculator

Calculate wet bulb temperature from dry bulb temperature and relative humidity. Stull empirical formula: T_wb = T·atan(0.151977√RH+8.313659) - atan(T+RH-1.676331) + ... Psychrometer and sling psychrometer use.

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 wet bulb temperature from dry bulb temperature and relative humidity. Stull empirical formula: T_wb = T·atan(0.151977√RH+8.313659) - atan(T+RH-1.676331) + ... Psychrometer and sling psychrometer use

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 wet bulb temp 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 wet bulb temperature from dry bulb temperature and relative humidity. Stull empirical formula: T_wb = T·atan(0.151977√RH+8.313659) - atan(T+RH-1.676331) + ... Psychrometer and sling psychrometer use. Use the wet bulb temp result to inform your clinical assessment.
