Modern, Material You psychrometrics.

• Calculate dry-bulb, wet-bulb, dew-point, and relative humidity.
• View humidity ratio, enthalpy, partial pressures, and specific volume.
• Switch seamlessly between Imperial and SI units, values convert automatically.
• Accurate formulas based on ASHRAE correlations and real-gas equations.
• Clean Material You interface with dynamic theming and light/dark support.

Ideal for HVAC technicians, engineers, students, and anyone working with air-conditioning, drying, or energy-efficiency analysis.

Sensible Heat / Cool

Model temperature changes at constant moisture content. PsychroCalc computes new state points, enthalpy differences, and flags condensation risk if the final condition crosses dew-point.

Adiabatic Mixing

Mix two airstreams (different temperature/humidity) with no external heat exchange. The app outputs the mixed dry-bulb, humidity ratio, RH, and enthalpy.
