Inputs

Dry Bulb Temperature (DBT) °F Altitude (ft) Calculate From Relative Humidity (RH) %

Temperature Conversion

Enter °C

Result °F —

Enter a value in °C to convert it to °F.

Location / Altitude

Indian City

Reference Altitude —

City selection sets the default Altitude input. You can override it for the actual project/site elevation.

Atmospheric Pressure —

Outputs

Wet Bulb Temperature (WBT) — °F

Relative Humidity (RH) — %

Humidity Ratio (W) — Gr/lb dry air

Dew Point Temperature — °F

Specific Enthalpy (h) — Btu/lb dry air

Specific Volume (v) — ft³/lb dry air

Air Density — lb/ft³

Psychrometric properties are calculated using DBT and either RH or WBT at the selected city altitude. Atmospheric pressure is estimated from standard-atmosphere altitude data. Enthalpy is reported per lb of dry air. Verify final engineering values against the applicable project standard before issue.
