Calculate comfort.

Features & Capabilities

Psychrometer °F is a Chrome extension that computes thermal comfort and essential air properties from simple dial inputs. Choose among three psychrometric types (Assmann, Natural, Sling), view color-coded temperatures, and assess whether conditions are in the comfortable range.

Enter values as temperature and humidity, dew point, or wet-bulb to derive dry-bulb temperature, dew point, relative humidity, vapor pressures, enthalpy, specific volume, and more. The app can auto-fetch outdoor weather data (with location permission), supports a wide input range, and includes notes on accuracy and limitations.

AI generated inappropriate ads

I have been using this app for about two month. The only fault I could find is the ads. Personally, I would like an option to pay for an ad-free version. But the developer had done a good job of minimizing the impact of the ad. I have checked the results against a thermodynamic program that I use for process simulation. The programs match up. I have found this app to be easy to use and intuitive. If one is an HVAC professional, this app and a good hygrometer are just what one needs to “get it right.” Way cool. UPDATE: I discovered that the developer has a different version called CalcComfort that includes a pro version that deletes ads and includes additional features like Frost point for temps below freezing. Excellent.
