Relative Humidity Calculator

Calculate relative humidity RH = (P_v/P_sat) × 100%. Convert between RH, specific humidity, humidity ratio, and vapor pressure. Find RH from dry and wet bulb temperatures using the psychrometric equation.

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 relative humidity RH = (P_v/P_sat) × 100%. Convert between RH, specific humidity, humidity ratio, and vapor pressure. Find RH from dry and wet bulb temperatures using the psychrometric equation

Each component has a specific meaning:

  • Dry — The dry recorded for the patient or scenario being assessed.
  • Wet bulb temperatures — The wet bulb temperatures recorded for the patient or scenario being assessed.

Note: Interpret the relative humidity result against the clinical thresholds and context described above.

How to Use

Enter the dry, wet bulb temperatures for the patient or scenario you are assessing. Calculate relative humidity RH = (P_v/P_sat) × 100%. Convert between RH, specific humidity, humidity ratio, and vapor pressure. Find RH from dry and wet bulb temperatures using the psychrometric equation. Use the relative humidity result to inform your clinical assessment.
